Answers

Answer 1

The problem involves analyzing distribution costs, selecting initial feasible solutions using different methods, and adapting the model to accommodate transportation constraints. The quantities produced by each refinery, requirements of each storage facility, and associated distribution costs are provided.

The objective is to determine an initial feasible solution and calculate the total cost using two different approaches: the Northwest Corner Rule and the Minimum Cell Cost method. Additionally, the problem states that transportation from Takoradi to Bawku is prohibited, requiring the formulation of a mathematical model to incorporate this constraint. To solve the distribution problem, a network graph can be created to represent the costs and decision variables. The Northwest Corner Rule is a method used to find an initial feasible solution. It starts by allocating the maximum possible amount from the northwest corner and iteratively filling in the remaining cells until all requirements are met. This method provides an initial solution based on the corner cells and their associated costs.

Alternatively, the Minimum Cell Cost method can be employed to find the initial feasible solution. This approach selects the cell with the lowest cost and assigns the maximum possible quantity. It continues to assign quantities based on the minimum cost cells until all requirements are fulfilled. By comparing the results obtained from both methods, it is possible to evaluate the differences in the total cost. The two approaches may yield different initial feasible solutions and subsequently different total costs. These variations highlight the importance of selecting an appropriate method and the impact it can have on the overall distribution cost. Considering the prohibition of transportation from Takoradi to Bawku, the mathematical model needs to be modified to incorporate this constraint. The formulation should exclude any allocation of gasoline from Takoradi to Bawku in the initial feasible solution and subsequent iterations.

Answer:

Base current increases and collector current decreases

Explanation:

Base current increases and collector current decreases

The collector current does reduces because electrons that moves from emitter to base and the electrons that moves from collector to base are both cancelled out. Some of these electrons enter from the emitter to the collector because, in a way, the emitter has been heavily döped

Discuss the exciton roles in silicon solar cell

Answers

Excitons play a crucial role in silicon solar cells and are involved in several processes that contribute to the generation of electricity. Here are some key roles of excitons in silicon solar cells:

1. Absorption of Photons: When photons from sunlight strike the silicon material of a solar cell, they can be absorbed by silicon atoms, promoting an electron from the valence band to the conduction band. This process creates an exciton—a bound electron-hole pair.

2. Exciton Diffusion: After absorption, excitons can diffuse through the silicon material, moving towards the region of the solar cell where charge separation occurs. This diffusion process allows excitons to reach the vicinity of the p-n junction, where the separation of charges takes place.

3. Exciton Dissociation: At the p-n junction of a silicon solar cell, excitons can undergo dissociation. The electric field created by the junction separates the electron and hole of the exciton, allowing them to move freely in opposite directions as charge carriers.

4. Electron and Hole Transport: Once the exciton is dissociated, the free electron and hole can move independently within the solar cell. They are transported through the silicon material to the respective electrodes, creating an electric current that can be harnessed for external use.

5. Recombination: Excitons can also undergo recombination, where the electron and hole recombine, releasing energy in the form of light or heat. Recombination is undesirable in solar cells as it reduces the overall efficiency of the device.

To enhance the efficiency of silicon solar cells, various strategies are employed to minimize exciton recombination and improve exciton dissociation and charge carrier transport. These include the use of anti-reflection coatings, surface passivation techniques, and optimization of the device structure.

Overall, excitons play a vital role in the absorption and conversion of sunlight into electrical energy in silicon solar cells. Understanding and controlling exciton dynamics are essential for improving the performance of solar cells and advancing the field of photovoltaics.

Thread, formed by spinning and twisting tibers together to hold the garment together. 'Therefore, the thread
the quality.

Answers

The thread is crucial for ensuring the quality and durability of the garment. It is formed by spinning and twisting fibers together, creating a continuous strand that is used to hold the various components of the garment together.

The quality of the thread directly affects the overall quality of the garment. A strong and well-constructed thread is essential for providing structural integrity and preventing the garment from unraveling or falling apart over time. It must be able to withstand the stresses and strains that occur during regular use, including stretching, pulling, and washing.

When choosing the appropriate thread for a garment, several factors are considered, including the type of fabric, the intended use of the garment, and the desired aesthetic. Different threads have varying levels of strength, elasticity, and resistance to abrasion. For example, a heavier fabric might require a thicker and more robust thread, while a delicate fabric may require a finer and more delicate thread to prevent damage.

The quality of the thread also relates to its consistency and uniformity. Irregularities in the thread's thickness or tension can result in uneven stitches, which may compromise the appearance and functionality of the garment. In addition, the thread's color and texture should be chosen carefully to complement the fabric and enhance the overall aesthetic appeal.

In the manufacturing process, quality control measures are implemented to ensure that the thread meets the required standards. This involves testing the thread for strength, colorfastness, and resistance to abrasion. By using high-quality thread and maintaining strict quality control, garment manufacturers can ensure that the final product meets or exceeds the expectations of customers in terms of both appearance and durability.

In summary, the thread plays a vital role in holding a garment together and contributes significantly to its quality and longevity. Choosing the right thread and ensuring its consistent quality throughout the manufacturing process are essential for creating garments that are durable, aesthetically pleasing, and able to withstand regular use.

2..Three formations, each 25 m thick, overlie one another. If a constant-velocity vertical flow field is set up across the set of formations with h = 120 m at the top and h = 100 m at the bottom, calculate h at the two internal boundaries. The hydraulic conductivity of the top formation is 0.0001 m/s, the middle formation 0.0005 m/s, and the bottom formation 0.0010 m/s.

Answers

The values of h at the two internal boundaries are :

h₁ = 104.625 m h₂ = 101.55 m

Given data :

Z₁ = Z₂ = Z₃ = 25 m

h top = 120 m

h bottom = 100 m

K₁ = 0.0001 m/s

K₂ = 0.0005 m/s

K₃ = 0.0010 m/s

First step : Calculate the value of Keq

we will apply the formula below since flow is perpendicular to the bedding plane

Keq = \(\frac{Z1 + Z2 + Z3 }{\frac{Z1}{K1}+\frac{Z2}{K2} + \frac{Z3}{K3} }\)  ----- ( 1 )

Insert values given above into equation 1

Therefore ; Keq = 2.307 * 10⁻⁴ m/s

Next step : determine the hydraulic gradient

Hydraulic gradient ( Ieq ) = head loss / length

                                          = ( 120 - 100 ) / 3 * 25

                                   Ieq  = 0.266

Given that the flow is perpendicular to bedding plane

q1 = q2 = q3

V₁ = V₂ = V₃ = V

K₁i₁ = K₂i₂ = K₃i₃ = Keq * ieq

Hence :

V = Keq* Ieq

   = 2.307 * 10⁻⁴ * 0.266

   = 6.15 * 10⁻⁵ m/s .

Also;

K₁i₁ =  Keq * ieq = K₂i₂ = K₃i₃

therefore :

  i₁ = 0.615

  i₂ =  0.123

  i₃ = 0.0615

Final step : determine the value of h at the two internal boundaries

Pressure at point 1 ( i.e. pressure between first two formations )

h₁ = h top - i₁L₁

   = 120 - 0.615 * 25

   = 104.625 m

Pressure at point 2 ( i.e. pressure between the 2nd and 3rd formation )

h₂ = h₁ - i₂L₂

    = 104.625 - 0.123 * 25

    = 101.55 m

Therefore we can conclude that The values of h at the two internal boundaries are :  h₁ = 104.625 m , h₂ = 101.55 m

A 19,400-N weight is raised using a jackscrew having a pitch of 5.00 mm and a handle length of 255 mm. What force must be applied?

Answers

To calculate the force required to lift a weight, we need to determine the mechanical advantage provided by the jackscrew. The mechanical advantage can be calculated as the ratio of the handle length to the pitch of the screw.

How to calculate the force required to lift a weight?

In this case, the mechanical advantage is:

255 mm / 5.00 mm = 51

This means that for every 51 turns of the handle, the screw will raise the load by a distance equal to the pitch of the screw, or 5.00 mm.

Now that we have the mechanical advantage, we can calculate the required force as follows:

Force = Weight / Mechanical Advantage

Force = 19,400 N / 51

Force = 380 N

So, a force of 380 N must be applied to the handle of the jackscrew to lift the 19,400 N weight.

Answers

The COP of the refrigeration cycle is 3.83, and the power required to service a 150 kW cooling load is 39.2 kW.

The given problem involves an ideal vapor-compression refrigeration cycle that uses refrigerant-134a as its working fluid. The condenser is maintained at 800 kPa, and the evaporator is at -20°C.

We need to determine the COP (Coefficient of Performance) and the power required to service a 150 kW cooling load. Firstly, we can determine the enthalpy change of the refrigerant during the cycle by using the saturation tables.

The enthalpy at the evaporator inlet is -129.2 kJ/kg, and at the condenser outlet is 214.5 kJ/kg. The COP can be calculated as the ratio of cooling effect to the work input, which is equal to the enthalpy change divided by the work input.

Thus, COP = (-129.2 - 214.5) / -129.2 = 3.83.

The power required to service the cooling load can be determined as the product of cooling load and COP.

When my animal is to old to physically carry her baby what process can I use to still produce her young from her

Answers

Taking care of" is a very human term in the sense of care giving, but so is "parents", because animals do not retain family structures in the form humans do. The vast majority of animals do not recognize family members. Among predators, an aging parent, such as the male lion in a pride, would continue to be taken care of by the females just as they always were, until a stronger outside male ousted it. An aging silverback in a group of gorillas would eventually be challenged and overthrown by one of his sons. When the elder became too infirm to care for itself, it would go off by itself to die. The only animal species that modify their behavior due to familial bonds to accommodate the needs of an aging member of the family are Cetaceans (whales) and Pachyderms (elephants). Whales have been seen to bouy up an ailing member of the pod (an extended family) to keep it from sinking. Elephants have the closest family ties of all animals, the eldest surviving female, the Matriarch of a herd, might be the great, great, great grandmother to the youngest and the others in varying relationships, are mothers, grandmothers, children, sisters, aunts and cousins, the older always taking care of and sheltering the younger. They also shelter and accommodate the older. If one member is sick or too old to keep up, the rest of the herd will slow down to allow the lagging one to keep up. This "caring" behavior has its limitations. The herd will not endanger itself to stay with an ailing member who will never be able to keep up. However, when the Matriarch herself is dying of old age, and the herd is in an area where food and water are abundant, the rest of the herd will stay with her, comfort her with their trunks, caressing her, talking to her, vocalizing over her, never leaving her side. While some are foraging, there will always be a group around her comforting her and expressing their love. (Scientists used to dismiss that term as inapplicable to animals, but the evidence is overwhelming that higher animal species have the same emotions humans do.) The herd will remain with her body, mourning, for several days, and years later will still return to fondle her bones with their trunks. Eventually one of the Matriarch's daughters will be chosen as the one to follow, or even two in which case the herd would divide into two new herds, the daughters and their offspring of each new Matriarch following their own family line.

The ACH​ (air changes per​ hour) of a house is a measure of its​ air-tightness. The formula for ACH is
ACH=60L/V​,
where L is the air leakage in cubic feet per minute​ (cfm), and V is the volume of the house in cubic feet. If a house has a volume of 25,700 cu​ ft, what is the maximum amount of air leakage that would result in an ACH of no more than 2.25​?
Answer: The maximum amount of air leakage that would result in an ACH of no more than 2.25 is approximately _______ cfm.

Answers

Answer: I believe the answer is 963.75 if I am reading the question right.

Explanation:

ACH=60L/V

ACH=2.25

V=25,700

25,700*2.25=57,825

57,825/60=963.75

L=963.75

60(963.75)/25,700=2.25

The maximum amount of air leakage that would result in an ACH of no more than 2.25 would be approximately 956.25 cfm (cubic feet per minute).

Given that ACH of a house is a measure of its​ air-tightness and the formula for ACH is ACH = 60L/V. It means that ACH is inversely proportional to air-tightness or leakage. Therefore, the lower the air leakage the higher the ACH and vice versa.Mathematically, it is represented as:ACH ∝ 1/L or L ∝ 1/ACH

We can solve the question as follows:ACH = 2.25 (since the maximum ACH is 2.25)The volume of the house, V = 25,700 cubic feet.Substituting in the formula,2.25 = 60L/25,700Dividing both sides by 2.25 gives us,L = (2.25 * 25,700)/60L = 956.25 cubic feet per minute (cfm)

Therefore, the maximum amount of air leakage that would result in an ACH of no more than 2.25 is approximately 956.25 cfm (cubic feet per minute).

Answer:

  (x, y) = (5.76, 1 5/7)

Explanation:

The location of the centroid in the x-direction is the ratio of the first moment of area about the y-axis to the total area. Similarly, the y-coordinate of the centroid is the first moment of area about the x-axis, divided by the area.

For the moment about the y-axis, we can define a differential of area as ...

  dA = (y2 -y1)dx

where y2 = √(x/k2) and y1 = k1·x^3

The distance of that area from the y-axis is simply x.

So, the x-coordinate of the centroid is ...

  \(\displaystyle c_x=\frac{a_x}{a}=\frac{\int{x\cdot dA}}{\int{dA}}\\\\a_x=\int_0^{12}{x(k_2^{-1/2}\cdot x^{1/2}-k_1x^3)}\,dx=\frac{2}{5k_2^{1/2}}\cdot12^{5/2}-\frac{k_1}{5}12^5\\\\a=\int_0^{12}{(k_2^{-1/2}\cdot x^{1/2}-k_1x^3)}\,dx=\frac{2}{3k_2^{1/2}}\cdot12^{3/2}-\frac{k_1}{4}12^4\\\)

For k1 = 4/12^3 and k2=12/4^2, these evaluate to ...

  \(a_x=115.2\\a=20\\c_x=5.76\)

The y-coordinate of the centroid requires we find the distance of the differential of area from the x-axis. We can use (y2 +y1)/2 for that purpose. Then the y-coordinate is ...

  \(\displaystyle c_y=\frac{a_y}{a}\\\\a_y=\int_0^{12}{(\frac{y_2+y_1}{2}(y_2-y_1))}\,dx=\frac{1}{2}\int_0^{12}{(\frac{x}{k_2}-(k_1x^3)^2)}\,dx\\\\a_y=\frac{12^2}{4k_2}-\frac{k_1^212^7}{14}=\frac{240}{7}\\\\c_y=\frac{12}{7}\approx1.7143\)

The centroid of the shaded area is ...

A lake with a surface area of 525 acres was monitored over a period of time. During onemonth period the inflow was 30 cfs (ie. ft3 /sec), the outflow was 27 cfs, and a 1.5 in seepage loss was measured. During the same month, the total precipitation was 4.25 inches. Evaporation loss was estimated as 6 inches. Estimate the storage change for this lake during the month.

Answers

Answer:

The storage of the lake has increased in \(4.58\times 10^{6}\) cubic feet during the month.

Explanation:

We must estimate the monthly storage change of the lake by considering inflows, outflows, seepage and evaporation losses and precipitation. That is:

\(\Delta V_{storage} = V_{inflow} -V_{outflow}-V_{seepage}-V_{evaporation}+V_{precipitation}\)

Where \(\Delta V_{storage}\) is the monthly storage change of the lake, measured in cubic feet.

Monthly inflow

\(V_{inflow} = \left(30\,\frac{ft^{3}}{s} \right)\cdot \left(3600\,\frac{s}{h} \right)\cdot \left(24\,\frac{h}{day} \right)\cdot (30\,days)\)

\(V_{inflow} = 77.76\times 10^{6}\,ft^{3}\)

Monthly outflow

\(V_{outflow} = \left(27\,\frac{ft^{3}}{s} \right)\cdot \left(3600\,\frac{s}{h} \right)\cdot \left(24\,\frac{h}{day} \right)\cdot (30\,days)\)

\(V_{outflow} = 66.98\times 10^{6}\,ft^{3}\)

Seepage losses

\(V_{seepage} = s_{seepage}\cdot A_{lake}\)

Where:

\(s_{seepage}\) - Seepage length loss, measured in feet.

\(A_{lake}\) - Surface area of the lake, measured in square feet.

If we know that \(s_{seepage} = 1.5\,in\) and \(A_{lake} = 525\,acres\), then:

\(V_{seepage} = (1.5\,in)\cdot \left(\frac{1}{12}\,\frac{ft}{in} \right)\cdot (525\,acres)\cdot \left(43560\,\frac{ft^{2}}{acre} \right)\)

\(V_{seepage} = 2.86\times 10^{6}\,ft^{3}\)

Evaporation losses

\(V_{evaporation} = s_{evaporation}\cdot A_{lake}\)

Where:

\(s_{evaporation}\) - Evaporation length loss, measured in feet.

\(A_{lake}\) - Surface area of the lake, measured in square feet.

If we know that \(s_{evaporation} = 6\,in\) and \(A_{lake} = 525\,acres\), then:

\(V_{evaporation} = (6\,in)\cdot \left(\frac{1}{12}\,\frac{ft}{in} \right)\cdot (525\,acres)\cdot \left(43560\,\frac{ft^{2}}{acre} \right)\)

\(V_{evaporation} = 11.44\times 10^{6}\,ft^{3}\)

Precipitation

\(V_{precipitation} = s_{precipitation}\cdot A_{lake}\)

Where:

\(s_{precipitation}\) - Precipitation length gain, measured in feet.

\(A_{lake}\) - Surface area of the lake, measured in square feet.

If we know that \(s_{precipitation} = 4.25\,in\) and \(A_{lake} = 525\,acres\), then:

\(V_{precipitation} = (4.25\,in)\cdot \left(\frac{1}{12}\,\frac{ft}{in} \right)\cdot (525\,acres)\cdot \left(43560\,\frac{ft^{2}}{acre} \right)\)

\(V_{precipitation} = 8.10\times 10^{6}\,ft^{3}\)

Finally, we estimate the storage change of the lake during the month:

\(\Delta V_{storage} = 77.76\times 10^{6}\,ft^{3}-66.98\times 10^{6}\,ft^{3}-2.86\times 10^{6}\,ft^{3}-11.44\times 10^{6}\,ft^{3}+8.10\times 10^{6}\,ft^{3}\)

\(\Delta V_{storage} = 4.58\times 10^{6}\,ft^{3}\)

The storage of the lake has increased in \(4.58\times 10^{6}\) cubic feet during the month.

The volume of water gained and the loss of water through flow,

seepage, precipitation and evaporation gives the storage change.

Response:

The storage change for the lake in a month is 1,582,823.123 ft.³

How can the given information be used to calculate the storage change?

Given parameters:

Area of the lake = 525 acres

Inflow = 30 ft.³/s

Outflow = 27 ft.³/s

Seepage loss = 1.5 in. = 0.125 ft.

Total precipitation = 4.25 inches

Evaporator loss = 6 inches

Number of seconds in a month is found as follows;

\(30 \ days/month \times \dfrac{24 \ hours }{day} \times \dfrac{60 \, minutes}{Hour} \times \dfrac{60 \, seconds}{Minute} = 2592000 \, seconds\)

Number of seconds in a month = 2592000 s.

Volume change due to flow, \(V_{fl}\) = (30 ft.³/s - 27 ft.³/s) × 2592000 s = 7776000 ft.³

1 acre = 43560 ft.²

Therefore;

525 acres = 525 × 43560 ft.² =  2.2869 × 10⁷ ft.²

Volume of water in seepage loss, \(V_s\) = 0.125 ft. × 2.2869 × 10⁷ ft.² = 2,858,625 ft.³

Volume gained due to precipitation, \(V_p\) = 0.354167 ft. × 2.2869 × 10⁷ ft.² = 8,099,445.123 ft.³

Volume evaporation loss, \(V_e\) = 0.5 ft. × 2.2869 × 10⁷ ft.² = 11,434,500 ft.³

\(Storage \, change \, \Delta V = \mathbf{V_{fl} - V_s + V_p - V_e}\)

Which gives;

ΔV = 7776000 - 2858625 + 8099445.123 - 11434500 = 1582823.123

The storage change, ΔV = 1,582,823.123 ft.³
