A 2 stage piston compressor has an intercooler where compressed air is cooled while passing to the second stage.

Answer:

Lack of oxygen

Decompression sickness

temperature variation

lack of gravity

Cosmic radiations hazards

motion sickness

Explanation:

When an astronaut travels in the space he is aware of the challenges he might face during his journey. There are various test and rehearsals of travelling before a final travel takes place. An astronaut goes through many challenges which includes lack of oxygen supply, decompression and motion sickness. There is no gravity in space so an astronaut will have to be aware of the difficulties he might face during his travel. An hour on earth is 7 years long in space, so an astronaut should have patience and be able to deal with time variation.

In high-volume turboprop and turbojet engines with two-spool or split compressors, the low-pressure rotor will increase in speed as the compressor load decreases in the lower density air at high altitudes. This is due to the difference in air pressure and density at higher altitudes, which affects the engine's performance.

1)A two-spool or split compressor system features separate high-pressure and low-pressure rotors. These rotors work independently to compress air, which allows the engine to achieve higher efficiency and performance. This design also improves the engine's response to varying altitude and air density conditions.

2)At high altitudes, the air density decreases, leading to a reduction in the compressor load. As the load on the compressor decreases, the low-pressure rotor can increase in speed to maintain the desired compression ratio and engine performance. This increase in speed allows the engine to adapt to the changing conditions and continue operating efficiently.

3)In summary, high-volume turboprop and turbojet engines with two-spool or split compressors can adjust their performance at high altitudes due to the increased speed of the low-pressure rotor as the compressor load decreases in the lower density air. This design feature enhances the engine's adaptability and efficiency in various operating conditions.

Answer:

There are five (5) unknown support reactions in this problem.

Explanation:

A roller joint rotates and translates along the surface on which the roller rests. The resulting reaction force is always a single force that is perpendicular to, and away from, the surface. This allows the roller to move in a single plane along the surface where it rests.

A cable support provides support in one direction, parallel, and in opposite direction to the load on it. There exists a single reaction from the cable pointed upwards.

A ball-and-socket joint have  reaction forces in all 3 cardinal  directions. This allows it to move in the x-y-z plane.

The total unknown reactions on the member are five in number.

The interior dimensions of the box in feet are approximately 1.47639 ft x 0.65617 ft x 0.24606 ft.

To determine the volume of air in the box, we first need to convert the given dimensions from meters to feet.

The interior dimensions of the box are 0.45 m x 0.2 m x 0.075 m.

Converting these dimensions to feet:

1 meter = 3.28084 feet

0.45 m x 3.28084 ft/m = 1.47639 ft

0.2 m x 3.28084 ft/m = 0.65617 ft

0.075 m x 3.28084 ft/m = 0.24606 ft

So, the interior dimensions of the box in feet are approximately 1.47639 ft x 0.65617 ft x 0.24606 ft.

Next, we need to calculate the total volume occupied by the twelve oranges. Each orange has a diameter of 2.5 inches, which gives a radius of 1.25 inches or 0.10417 ft (since 1 inch = 0.08333 ft).

The volume of a single orange can be calculated using the formula for the volume of a sphere:

V = (4/3) * π * r^3

Substituting the radius (0.10417 ft) into the formula:

V_single_orange = (4/3) * π * (0.10417 ft)^3

Now, to find the total volume occupied by twelve oranges:

V_total_oranges = V_single_orange * 12

Finally, to determine the volume of air in the box, we subtract the total volume occupied by the oranges from the total volume of the box:

V_air = (1.47639 ft * 0.65617 ft * 0.24606 ft) - V_total_oranges

Calculating the values and subtracting the volumes, we find the volume of air in the box in cubic feet.

Please note that the result may vary slightly due to rounding off the decimal places during the calculations.

Answer:

the process capability index for the precision machining process is 0.667

Explanation:

Given the data in the question;

Lower Specification Limits LSL = 0.99 mm

Upper Specification Limits USL = 1.01 mm.

The standard deviation σ = 0.005 mm

mean μ = 1 mm

capability index Cpk = ?

Cpk = min( USL - μ / 3σ, μ - LSL / 3σ )

we substitute

Cpk = min( 1.01 mm - 1 mm / 3(0.005 mm ), 1 - 0.99 mm / 3(0.005 mm) )

Cpk = min( 0.01 mm / 0.015 mm, 0.01 mm / 0.015 mm )

Cpk = min( 0.6666, 0.6666 )

∴ Cpk = 0.6666 ≈ 0.667

Therefore, the process capability index for the precision machining process is 0.667

The functionality that is easier to accomplish using an ArrayList instead of an array is dynamic resizing.

In an array, the size is fixed and cannot be changed once it is declared. If the programmer wants to add or remove an element from the array, they must create a new array with a larger or smaller size and copy the existing elements into the new array. This process can be time-consuming and can waste memory if the new array is significantly larger than the original.

An ArrayList, on the other hand, is a resizable array. It can dynamically resize itself to accommodate the addition or removal of elements. This makes it easier to add or remove elements from the list without having to create a new array each time. The ArrayList class provides methods such as add(), remove(), and clear() that simplify the process of adding, removing, or modifying elements in the list.

Another advantage of using an ArrayList is that it can store objects of any data type, whereas an array can only store elements of a single data type. This makes ArrayList more flexible and versatile than arrays.

In summary, an ArrayList provides easier dynamic resizing and more flexibility compared to arrays.

Answer:

Explanation:

Step one:

given data

V1=0.25m^3

T1=290k

P1=100kPa

V2=0.5m^2

T2=405k

P2=? final pressure

Step two:

The combined gas equation is given as

P1V1/T1=P2V2/T2

Substituting we have

(100*0.25)/290=P2*0.05/405

25/290=0.5P2/405

0.086=0.05P2/405

cross multiply

0.086*405=0.05P2

34.9=0.05P2

divide both sides by 0.05

P2=34.9/0.05

P2=698.3Kpa

Therefore the new pressure is 698.3Kpa when the gas is compressed

The given statement "If a system is not selectively coordinated, unnecessary power loss can occur to loads that otherwise should be unaffected" is True because the fault occurs, only the portion of the system affected by the fault is shut off, rather than the entire system.

Selective coordination is a method of protecting electrical power systems by ensuring that only the circuit breaker or fuse that is closest to the fault opens, leaving the rest of the system intact. When a system is not selectively coordinated, faults can result in unnecessary power loss to loads that should not be affected, leading to reduced efficiency and increased operating costs.

For example, consider a large commercial building with multiple electrical panels, each serving a different section of the building. If a fault occurs in one panel, a non-selectively coordinated system may cause the main breaker for the entire building to trip, cutting power to all sections, even those that were not affected by the fault. This can result in a significant loss of power to critical loads and systems, leading to downtime, lost productivity, and potentially costly repairs.

In contrast, a selectively coordinated system would isolate the fault to the specific panel where it occurred, leaving the rest of the building unaffected. This ensures that power is maintained to critical loads and systems, while also reducing downtime and repair costs. Overall, selective coordination is an essential aspect of maintaining efficient and reliable electrical power systems.

Assuming you forgot how to solve linear equations, and don't remember arithmetic with complex numbers, we can solve this "by hand" as follows. It is convenient to write the equations in standard form to start:

  (2+j6)I₁ -j4I₂ = 0

  jI₁ +(8 -j10)I₂ = 2

We can eliminate the I2 variable by multiplying the second equation by j4 and the first equation by (8-j10) and adding the result.

  (8 -j10)((2 +j6)I₁ -j4I₂) +(j4)(jI₁ +(8-j10)I₂) = (8 -j10)(0) +(j4)(2)

  I₁(8·2 +10·6 -4 +j(-10·2 +8·6)) +I₂(0) = j8

  I₁ = j8/(72+j28) = j2/(18 +j7) = (j2)(18 -j7)/(18² +7²)

  I₁ = (14 +j36)/373

Similarly, we can eliminate the I₁ variable by multiplying the second equation by (2+j6) and the first equation by -j, then adding the results.

  -j((2 +j6)I₁ -j4I₂) +(2+j6)(jI₁ +(8-j10)I₂) = -j(0) +(2 +j6)(2)

  0·I₁ +(-4 +2·8 +6·10 +j(6·8 -2·10))I₂ = 4 +j12

  I₂(72 +j28) = 4 +j12

  I₂ = (1 +j3)/(18 +j7) = (1 +j3)(18 -j7)/(18² +7²)

  I₂ = (39 +j47)/373

The polar conversion is done in the usual way:

  a +jb = √(a² +b²) ∠ arctan(b/a)

  I₁ = √(14² +36²)/373 ∠ arctan(36/14)

  I₁ ≈ 0.103556∠68.749°

  I₂ = √(39² +47²)/373 ∠ arctan(47/39)

  I₂ ≈ 0.163737∠50.315°

Explanation:

Answer:

The wind turbine generates \(19297.222\) kilowatt-hours of electricity daily.

The wind turbine makes a daily revenue of 1736.75 US dollars.

Explanation:

First, we have to determine the stored energy of wind (\(E_{wind}\)), measured in Joules, by means of definition of Kinetic Energy:

\(E_{wind} = \frac{1}{2}\cdot \dot m_{wind}\cdot \Delta t \cdot v_{wind}^{2}\) (Eq. 1)

Where:

\(\dot m_{wind}\) - Mass flow of wind, measured in kilograms per second.

\(\Delta t\) - Time in which wind acts in a day, measured in seconds.

\(v_{wind}\) - Steady wind speed, measured in meters per second.

By assuming constant mass flow and volume flows and using definitions of mass and volume flows, we expand the expression above:

\(E_{wind} = \frac{1}{2}\cdot \rho_{air}\cdot \dot V_{air} \cdot \Delta t \cdot v_{wind}^{2}\) (Eq. 1b)

Where:

\(\rho_{air}\) - Density of air, measured in kilograms per cubic meter.

\(\dot V_{air}\) - Volume flow of air through wind turbine, measured in cubic meters per second.

\(E_{wind} = \frac{1}{2}\cdot \rho_{air}\cdot A_{c}\cdot \Delta t\cdot v_{wind}^{3}\) (Eq. 2)

Where \(A_{c}\) is the area of the wind flow crossing the turbine, measured in square meters. This area is determined by the following equation:

\(A_{c} = \frac{\pi}{4}\cdot D^{2}\) (Eq. 3)

Where \(D\) is the diameter of the wind turbine blade, measured in meters.

If we know that \(\rho_{air} = 1.25\,\frac{kg}{m^{3}}\), \(D = 100\,m\), \(\Delta t = 86400\,s\) and \(v_{wind} = 8\,\frac{m}{s}\), the stored energy of the wind in a day is:

\(A_{c} = \frac{\pi}{4}\cdot (100\,m)^{2}\)

\(A_{c} \approx 7853.982\,m^{2}\)

\(E_{wind} = \frac{1}{2}\cdot \left(1.25\,\frac{kg}{m^{3}} \right) \cdot (7853.982\,m^{2})\cdot (86400\,s)\cdot \left(8\,\frac{m}{s} \right)^{3}\)

\(E_{wind} = 2.171\times 10^{11}\,J\)

Now, we proceed to determine the quantity of energy from wind being used by the wind turbine in a day (\(E_{turbine}\)), measured in joules, with the help of the definition of efficiency:

\(E_{turbine} = \eta\cdot E_{wind}\) (Eq. 4)

Where \(\eta\) is the overall efficiency of the wind turbine, dimensionless.

If we get that \(E_{wind} = 2.171\times 10^{11}\,J\) and \(\eta = 0.32\), then the energy is:

\(E_{turbine} = 0.32\cdot (2.171\times 10^{11}\,J)\)

\(E_{turbine} = 6.947\times 10^{10}\,J\)

The wind turbine generates \(6.947\times 10^{10}\) joules of electricity daily.

A kilowatt-hours equals 3.6 million joules. We calculate the equivalent amount of energy generated by wind turbine in kilowatt-hours:

\(E_{turbine} = 6.947\times 10^{10}\,J\times\frac{1\,kWh}{3.6\times 10^{6}\,J}\)

\(E_{turbine} = 19297.222\,kWh\)

The wind turbine generates \(19297.222\) kilowatt-hours of electricity daily.

Lastly, the revenue generated per day can be found by employing the following:

\(C_{rev} = c\cdot E_{turbine}\) (Eq. 5)

Where:

\(c\) - Unit price, measured in US dollars per kilowatt-hour.

\(C_{rev}\) - Revenue generated by the wind turbine in a day, measured in US dollars.

If we know that \(c = 0.09\,\frac{USD}{kWh}\) and \(E_{turbine} = 19297.222\,kWh\), then the revenue is:

\(C_{rev} = \left(0.09\,\frac{USD}{kWh} \right)\cdot (19297.222\,kWh)\)

\(C_{rev} = 1736.75\,USD\)

The wind turbine makes a daily revenue of 1736.75 US dollars.
