The initial pressure in the cylinder of 10 bar of argon with [tex]C_p[/tex] = (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;

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

Where;

[tex]k = \dfrac{C_p}{C_v} = \mathbf{\dfrac{C_p}{C_p - R}}[/tex]

Therefore;

[tex]K= \mathbf{\dfrac{\frac{5}{2} \cdot R}{\frac{5}{2} \cdot R - R} }= \dfrac{5}{3}[/tex]

Which gives;

[tex]\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}[/tex]

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

[tex]ln(5)= 2.5\cdot ln\left (\dfrac{T_2}{298.15} \right )[/tex]

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

The temperature

Using an ideal gas model, we have;

[tex]\dfrac{V_{1}}{V_{2}} = \mathbf{\dfrac{P_{2}\times T_{1}}{T_{2} \times P_1}}[/tex]

Which gives;

[tex]\dfrac{V_{1}}{V_{2}} = \dfrac{50\times 298}{567.29 \times 10} \approx 2.625[/tex]

V₁ = 2.625·V₂

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

[tex]V_2 = \dfrac{V_1}{2.625} \approx 0.381 \cdot V_1[/tex]

Volume of gas added is therefore;

[tex]V =V_1 - \dfrac{V_1}{2.625} = 0.619\cdot V_1[/tex]

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;

[tex]\dfrac{P_1}{T_1} = \mathbf{\dfrac{P_2}{T_2}}[/tex]

Which gives;

[tex]P_2= \mathbf{\dfrac{P_1}{T_1} \times T_2}[/tex]

Therefore;

[tex]P_2= \dfrac{50}{400.6} \times 298 \approx 37.194[/tex]

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

Answer:

Both helpful and harmful

Explanation:

The milkweed plant is helpful, because it is the host pant for monarch butterflies and helps provide nectar and pollen for many other pollinators.

It is harmful for many reasons, including it's toxic, poisonous, it produces a type of steroid that is able to stop the heart, and they cause many other sicknesses.

Based on the two things above, milkweed plants are both helpful and harmful to the environment.

It is helpful because the milkweed plants acts as source of food for the caterpillar while it is harmful because it kills other plants around it.

This plant is known to belong to the genus  of herbaceous plant. It is called Asclepias as it is a perennial, flowering plants.

It is said to derive its name from latex, that is a milky substance that comes out of it when cells are damaged. monarch caterpillars needs to eat milkweed so that they can survive.

Answer:

  (a) 16.27 Vpk

  (b) 48.7%

Explanation:

The transformer is assumed to be an ideal 10:1 voltage divider with no internal impedance. The diode is assumed to be modeled in the forward direction by a perfect 0.7 V voltage drop with no internal impedance. That means the frequency of the supply voltage is irrelevant.

__

The peak voltage will be 0.7 V less than the transformer secondary peak voltage:

  ((120 V)√2)/10 -0.7 V ≈ 16.27 V

__

The fraction of the amplitude for which the diode is non-conducting is ...

  0.7/(12√2) ≈ 0.041248

The period of conduction is symmetrical about the peak of the waveform, so it is convenient to use the arccos function to find the (half) conduction angle:

  arccos(0.041248) ≈ 87.64°

As a fraction of half the cycle, this is ...

  conduction fraction ≈ 87.64°/180° ≈ 48.7%

I am sorry. I don't understand too :/ I haven't learn engineering before- But if I'm not wrong, if something is black, probably it's burnt? Because you have to dip it in the water to cool down.

For example, if a steel is burnt, it will change color like blue.

So the answer is "burnt".

Having a bluish or black color of the material means it is burnt so dip it in the water to cool down

Answer:

Message packet

Explanation:

The ans is message packet

The correct option is D. Packet switching​ is a method of switching in which the message is divided into small packets.

The message is broken into smaller pieces when using packet switching. Each of these discrete components of the communication, known as packets, has a unique source and destination address. Only based on these addresses is each packet sent forward through the network.

The method through which nodes control or switch data to send it between particular places on a network is known as switching. There are three typical switching methods: Switching a circuit. Switching of packets. Switching messages.

Small data packets are sent between different networks using packet switching. These data "packets" or "chunks" enable quicker, more effective data transport. When a user transfers a file over a network, it frequently travels in smaller data packets rather than all at once.

Thus, the correct option is represented by option D. In the packet switching method the message is divided into small packets.

The maximum value of rolling resistance over which a loaded scraper can maintain in a speed of 11 mph is 275 lb/ton

The maximum rolling resistance is the maximum rolling friction that can cause the motion of a body or a substance to resist the force when rolled on a flat surface.

Using Rimpull Performance Chart for wheel-tractor scraper;

The total resistance = (gross+rolling) resistance

25% = 0% - rolling resistance

rolling resistance = 25%

The maximum rolling resistance = rolling resistance percentage × speed

The maximum rolling resistance [tex]\mathbf{=25\% ( \dfrac{11 \ lb/ton}{1 \% \ resistance})}[/tex]

Answer:

  16 minutes

Explanation:

This is an example of a class of problems in which two quantities start with different initial values and change at different rates. In such problems, the rates of change are generally ones that cause the values to converge.

The question usually asks when the values will be the same. The generic answer is, "when the difference in rates makes up the difference in initial values."

Here the tanks differ in initial fill height by 12 -8 = 4 ft. The rates of change differ by 0.5 -0.25 = 0.25 ft/min. The more filled tank is draining faster (important), so the fill heights will converge after ...

  (4 ft)/(0.25 ft/min) = 16 min

The level in the two tanks will be the same after 16 minutes.

__

Additional comment

The oil levels at that time will be 4 ft.

You can write two equations for height:

  y = 12 -0.5x . . . . . . . height in feet after x minutes (tank A)

  y = 8 -0.25x . . . . . .  height in feet after x minutes (tank B)

These will be equal when ...

  y = y

  12 -0.5x = 8 -0.25x

  4 = 0.25x . . . . . . . . . . add 0.5x -8

  16 = x . . . . . . . . . . . . multiply by 4 . . . . time to equal height

The graph shows when the tanks will have equal heights and when they will be drained.

The profit that will be made for the first and second years will be $100,000 and $460,000.

The profit of the graphics company for the first year will be:

= 4(100000) - [200000 + 100000]

= 400000 - 300000

= 100000

The profit for the second year will be:

Answer:

Here the operating conditions of the transistor are zero input base current ( IB ), zero output collector current ( IC ) and maximum collector voltage ( VCE ) which results in a large depletion layer and no current flowing through the device. Therefore the transistor is switched “Fully-OFF”.

2.Saturation Region

Here the transistor will be biased so that the maximum amount of base current is applied, resulting in maximum collector current resulting in the minimum collector emitter voltage drop which results in the depletion layer being as small as possible and maximum current flowing through the transistor. Therefore the transistor is switched “Fully-ON”.
