The initial pressure in the cylinder of 10 bar of argon with \(C_p\) = (5/2)·R

and the added gas at pressure of 50 bar gives the following values.

(a) 400.6 K

(b) 51.184 J

(c) The pressure of the cylinder when it is shipped is 37.194 bar

(a) Adiabatic compression, we have;

\(\dfrac{p_{1}}{p_{2}} = \mathbf{\left (\dfrac{T_{_{1}}}{T_{2}} \right )^{\dfrac{k}{k-1}}}\)

Where;

\(k = \dfrac{C_p}{C_v} = \mathbf{\dfrac{C_p}{C_p - R}}\)

Therefore;

\(K= \mathbf{\dfrac{\frac{5}{2} \cdot R}{\frac{5}{2} \cdot R - R} }= \dfrac{5}{3}\)

Which gives;

\(\dfrac{10}{50} = \left (\dfrac{298}{T_{2}} \right )^{\dfrac{\frac{5}{3} }{\frac{5}{3} -1}} = \left (\dfrac{298}{T_{2}} \right )^{2.5}\)

\(\dfrac{50}{10} = \mathbf{ \left (\dfrac{T_2}{298.15} \right )^{2.5}}\)

\(ln(5)= 2.5\cdot ln\left (\dfrac{T_2}{298.15} \right )\)

\(T_2 = 298 \times e^{\dfrac{ln(5)}{2.5} } \approx \mathbf{567.29\, K}\)

The temperature

Using an ideal gas model, we have;

\(\dfrac{V_{1}}{V_{2}} = \mathbf{\dfrac{P_{2}\times T_{1}}{T_{2} \times P_1}}\)

Which gives;

\(\dfrac{V_{1}}{V_{2}} = \dfrac{50\times 298}{567.29 \times 10} \approx 2.625\)

V₁ = 2.625·V₂

Volume occupied by the gas in the cylinder after the pressure increases is therefore;

\(V_2 = \dfrac{V_1}{2.625} \approx 0.381 \cdot V_1\)

Volume of gas added is therefore;

\(V =V_1 - \dfrac{V_1}{2.625} = 0.619\cdot V_1\)

Considering a molar volume of gas, we have;

0.040 × 0.619 × 2.5×8.3145×(T₃ - 298) = 0.040 × 0.381 × 2.5×8.3145×(567.29 - T₃)

Solving gives;

T₃ ≈ 400.6 K

For a molar volume of gas cylinder, the temperature just after the valve is closed is T₃ ≈ 400.6 K

(b) If the cylinder sits in the storage for a long time, and heat is conducted out, we have;

The temperature of the cylinder will revert to room temperature of 298 K

The heat transferred is therefore;

0.040 × (2.5 × 8.3145 - 8.3145) ×(400.6 - 298) ≈ 51.184

The heat transferred from the cylinder is 51.184 J

(c) The pressure of the gas in the cylinder is therefore;

\(\dfrac{P_1}{T_1} = \mathbf{\dfrac{P_2}{T_2}}\)

Which gives;

\(P_2= \mathbf{\dfrac{P_1}{T_1} \times T_2}\)

Therefore;

\(P_2= \dfrac{50}{400.6} \times 298 \approx 37.194\)

The pressure of the cylinder when it is shipped is 37.194 bar

Answer:

The secondary coil should have fewer turns compared to the primary coil.

Explanation:

\(N_p\) = Number of turns in primary coil = 300

\(N_s\) = Number of turns in secondary

\(V_p\) = Voltage in primary coil = 120 V

\(V_s\) = Voltage in secondary coil = 6.4 V

We have the relation

\(\dfrac{N_p}{N_s}=\dfrac{V_p}{V_s}\\\Rightarrow N_s=\dfrac{N_p}{V_p}\times V_s\\\Rightarrow N_s=\dfrac{300}{120}\times 6.4\\\Rightarrow N_s=16\)

If it is subjected to the couple determine the maximum shear stress in regions AC and CB of the shaft. G st = 75 GPa. Than the answer will be 52Mpa.

We need to perform a two step process to obtain the maximum shear stress on the shaft. For the solid shaft,

P=2×pi×N×T/60 or T=60×p/2×pi×N

Where P=power transmitted by the shaft=50×10³W

N=rotation speed of the shaft in rpm=730rpm

Pi=3.142

T is the twisting moment

By substituting the values for pi, N and P, we get

T=654Nm or 654×10³Nmm

Also, T=pi×rho×d³/16 or rho=16×T/pi×d³

Where rho=maximum shear stress

T = twisting moment=654×10³Nmm

d= diameter of shaft= 40mm

By substituting T, pi and d

Rho=52Mpa

b. For a hollow shaft, the value for rho is unknown

T=pi×rho(do⁴-di⁴/do)/16

Rho=T×16×do/pi×(do⁴-di⁴)

Where

T= twisting moment=654×10³Nmm gotten above

do=outside shaft diawter=40mm

di= inside shaft diameter =30mm

Pi=3.142

Substituting values for pi, do, di and T.

An environmental hazard is a substance, state or event which has the potential to threaten the surrounding natural environment and/or adversely affect human's health. This term incorporates topics like pollution, natural disasters and human-made hazards. Health studies investigate the human health effects of exposure to environmental hazards ranging from chemical pollutants to natural, technological or terrorist disasters. The environment in which we live can be considered as having three fundamental sets of components, physical, chemical, biological. Associations between an exposure and an adverse health effect do not, on their own, prove that the former is the cause of the latter. Many other non-causal associations could explain the findings. Physical hazards involve environmental hazards that can cause harm with or without contact. Examples are earthquakes, electromagnetic fields, floods, light pollution, noise pollution, vibration, x-rays etc. Radioactivity is associated with an exposure dependent risk of some cancers notably leukaemia. The scientific evidence of adverse health effects from general environmental exposure to these fields is "not proven". If there are adverse effects yet to be proven, the risk is probably likely to be small. Chemical substances cause significant damage to the environment. Tobacco smoke is the single biggest known airborne chemical risk to health, whether measured in terms of death rates or ill-health. To a much lesser degree of risk, these adverse effects apply to non-smokers exposed passively to sidestream tobacco smoke. Health effects of concern are asthma, bronchitis, lung cancer and similar lung diseases, and there is good evidence relating an increased risk of symptoms of these diseases with increasing concentration of Sulphur dioxide, ozone and other pollutants. Biohazards generally fall into two broad categories: those which produce adverse health effects through infection (microorganisms, viruses or toxins) and those which produce adverse effects in non-infective (allergic) ways.

Answer:

the magnitude of the velocity when t = 3 s is 10.54 m/s.

Explanation:

To solve this problem, we can use the following kinematic equation that relates velocity, acceleration, and time:

v = vo + at

where:

v = final velocity

vo = initial velocity

a = acceleration

t = time

First, we need to find the velocity of the object at time t = 3 s. To do this, we can substitute the given values into the kinematic equation and solve for v:

v = vo + at

v = 8i + (-0.2i+2j+1.5k) x 3

v = 8i - 0.6i + 6j + 4.5k

v = 7.4i + 6j + 4.5k

The magnitude of the velocity is given by:

|v| = sqrt(vx^2 + vy^2 + vz^2)

where:

vx, vy, vz = the x, y, and z components of the velocity vector

Substituting the values from above, we get:

|v| = sqrt((7.4)^2 + 6^2 + (4.5)^2)

|v| = sqrt(54.81 + 36 + 20.25)

|v| = sqrt(111.06)

|v| = 10.54 m/s (approx)

The difference equation of the overall system can be found by taking the inverse Z-transform of the product of the two transfer functions and the impulse response by taking the inverse Z-transform of the resulting d.e.

The overall system can be represented by H1(e^jw)H2(e^jw), where H1(e^jw) is the frequency response of the first LTI system and H2(e^jw) is the frequency response of the second LTI system. The difference equation describing the overall system can be obtained by taking the inverse Z-transform of the product of H1(e^jw) and H2(e^jw).

Thus, the difference equation of the overall system is given by y[n] - y[n-1] + 2x[n] - 2x[n-1] + x[n-2] = 0, where y[n] and x[n] are the output and input signals of the overall system, respectively.

To determine the impulse response of the overall system, we can set x[n] = δ[n], where δ[n] is the unit impulse function. Thus, the difference equation reduces to y[n] - y[n-1] + 2δ[n] - 2δ[n-1] + δ[n-2] = 0.

Taking the Z-transform of this equation, we get Y(z)(1 - z^-1) + 2(1 - z^-1) - 2z^-1 + z^-2 = 0. Rearranging and solving for Y(z), we obtain Y(z) = (2 - z^-1)/(1 - z^-1 + z^-2).

Finally, taking the inverse Z-transform of Y(z), we obtain the impulse response of the overall system as h[n] = 2^n u[n] - (2^n-1)u[n-1], where u[n] is the unit step function.

Explanation:

Since no figure was given, I'll explain how to do this problem theoretically. The formula for shear flow is \(q=\frac{VQ}{I}\) where V is the shear force, Q is the moment of area (more on this later), and I is the moment of inertia.

The first step to solve this problem is to find the resultant internal forces of the beam. This can be done in several ways, but the easiest is to solve the beam statically and draw a shear diagram to determine the maximum shear force V.

The second step to solving this problem is to determine the location of the neutral axis of the cross section if it is not given. The formula for the neutral axis is  \(NA = \frac{\sum y*A}{\sum A}\). The y in this equation represents the middle of the small shapes that the web is divided into. An I-beam can be thought of as 3 rectangles, while a T-beam can be thought of as 2. The A in this formula represents the area of each of the rectangles (an I-beam will have 3 of these and a T-beam will have 2).

The third step for this problem is to find the moment of inertia. There are several formulas for moment of inertia depending on the shape of the cross section. I-beam's and T-beams both can be thought of as multiple rectangles, so they have the same base formula of \(I=\frac{1}{12}bh^3\) where b is the base of the rectangles and h is the height. For I-beams, the easiest way to calculate moment of inertia is to think of the entire cross section as a big rectangle that had two smaller rectangles cut out of it. The formula for this moment of inertia becomes \(I=\frac{1}{12} b_{big}h^{3} _{big}-\frac{1}{6}b_{small}h^{3}_{small}\). Note that this form of moment of inertia already takes into account subtracting 2 small rectangles. For T-beams, this approach will not work, so the parallel axis theorem must be used. The moment of inertia for the T-beam becomes \(I=\frac{1}{12}b_{1} h^{3}_{1} +b_{1}h_{1}dy_{1}^{2} +\frac{1}{12}b_{2} h^{3}_{2} +b_{2}h_{2}dy_{2}^{2}\) where the terms with the subscript 1 represent the first rectangle and the terms with the subscript 2 represent the second rectangle. The dy terms represent the distance from the center of that specific rectangle to the neutral axis.

The fourth step for this problem is to find Q. The formula to find Q is \(Q=\sum y'A'\) where y' represents the distance from the neutral axis to the center of the "wanted" point and A' is the area of the rectangle that has the wanted point at its center. (This would be the area above or below the thickness (t) if you were solving for maximum shear \(\tau=\frac{VQ}{It}\)).

The last step for this problem is to substitute the found values into the formula for shear flow \(q=\frac{VQ}{I}\). V came from step 1, Q came from step 4, and I came from step 3.

Where the above conditions exists, the DC resistance at 50°C with skin effect is 77.2% higher than the DC resistance at 50°C without skin effect.

To calculate the DC resistance at 20°C, we can use the given dc resistance per 1000 ft:

DC resistance per ft = (0.01558 ohm / 1000 ft) * (1113 kcmil / 1000 cmil)

= 0.01735 ohm/ft

Next, we need to account for the 2% increase in resistance due to spiraling:

Resistance increase due to spiraling = 2% * 0.01735 ohm/ft

= 0.000347 ohm/ft

Therefore, the total DC resistance at 20°C is:

DC resistance at 20°C = 0.01735 ohm/ft + 0.000347 ohm/ft

= 0.017697 ohm/ft

To calculate the DC resistance at 50°C, we need to use the temperature coefficient of resistance for aluminum, which is 0.00403/°C. The resistance at 50°C can be found using the following formula:

R(50) = R(20) [1 + α(50 - 20)]

where R(20) is the DC resistance at 20°C and

α is the temperature coefficient of resistance for aluminum.

R(50) = 0.017697 ohm/ft [1 + 0.00403/°C * (50°C - 20°C)] = 0.019371 ohm/ft

The percentage increase due to skin effect can be calculated using the following formula:

% increase due to skin effect = 100 * (R(50) - R(dc)) / R(dc)

where R(dc) is the DC resistance at 50°C without skin effect.

R(dc) = 0.0956 ohm/mile * 5280 ft/mile / 61 strands

= 0.08503475442 ohm/ft

% increase due to skin effect = 100 * (0.019371 ohm/ft - 0.08503475442 ohm/ft) / 0.08503475442 ohm/ft

= 77.2%

The maximum allowable discharge for the road is 0.225 m³/s with a depth of 3.0 meters. Adding a gutter depression doesn't change the capacity, which remains at 0.18 m³/s with a depth of 3.0 meters.

To calculate the maximum allowable discharge and the depth of flow for the given road conditions, let's follow the steps:

Step 1: Calculate the cross-sectional area of flow for the road without the gutter depression.

The cross-slope of the road is 2.5%, which means for every meter of horizontal distance, there is a rise of 2.5 cm.

Cross-sectional area = road width * road cross-slope

                  = 3.0 m * (2.5/100)

                  = 0.075 m²

Step 2: Calculate the maximum allowable discharge on the road without the gutter depression.

The maximum allowable discharge is limited by the spread, which is 3.0 m.

Maximum allowable discharge = cross-sectional area * spread

                          = 0.075 m² * 3.0 m

                          = 0.225 m³/s

Step 3: Calculate the depth of flow at the curb for this rate of discharge.

To find the depth of flow, we need to divide the discharge by the cross-sectional area.

Depth of flow = Maximum allowable discharge / cross-sectional area

            = 0.225 m³/s / 0.075 m²

            = 3.0 m

Therefore, the depth of flow at the curb for the maximum allowable discharge is 3.0 meters.

Step 4: Calculate the maximum allowable discharge and the depth of flow for the road with the gutter depression.

The gutter depression has a width of 1.5 meters and a cross-slope of 4.0%.

Cross-sectional area of the gutter = gutter width * gutter cross-slope

                                = 1.5 m * (4.0/100)

                                = 0.06 m²

Maximum allowable discharge in the gutter = cross-sectional area of the gutter * spread

                                        = 0.06 m² * 3.0 m

                                        = 0.18 m³/s

Depth of flow in the gutter = Maximum allowable discharge in the gutter / cross-sectional area of the gutter

                          = 0.18 m³/s / 0.06 m²

                          = 3.0 m

The depth of flow in the gutter is also 3.0 meters.

Step 5: Determine the effect of the gutter depression on the capacity of the gutter.

The addition of the gutter depression does not increase or decrease the capacity of the gutter. The capacity remains the same at a maximum allowable discharge of 0.18 m³/s and a depth of flow of 3.0 meters. The purpose of the gutter depression is to provide a channel for efficient water drainage, but it does not affect the overall capacity of the gutter.

To summarize:

- The maximum allowable discharge on the road without the gutter depression is 0.225 m³/s, and the depth of flow at the curb is 3.0 meters.

- The maximum allowable discharge in the gutter with the gutter depression is 0.18 m³/s, and the depth of flow in the gutter is also 3.0 meters.

- The addition of the gutter depression does not affect the capacity of the gutter; it provides efficient drainage without altering the maximum allowable discharge or depth of flow.
