2) The switch in the circuit below has been closed a long time. At t=0, it is opened.Find the inductor current for il(t) for t> 0.
Answers
Answer:
il(t) = e^(-100t)
Explanation:
The current from the source when the switch is closed is the current through an equivalent load of 15 + 50║50 = 15+25 = 40 ohms. That is, it is 80/40 = 2 amperes. That current is split evenly between the two parallel 50-ohm resistors, so the initial inductor current is 2/2 = 1 ampere.
The time constant is L/R = 0.20/20 = 0.01 seconds. Then the decaying current is described by ...
il(t) = e^(-t/.01)
il(t) = e^(-100t) . . . amperes

Look below the oncoming headlights when a car with bright headlights comes toward you at night.
When a car with bright headlights comes toward you at night, you should look below the oncoming headlights.
This is because looking directly into the bright lights can temporarily impair your vision and make it difficult to see the road ahead. By looking slightly below the headlights, you can still maintain visibility of the road while minimizing the direct glare.
Moving toward the right edge of your lane or focusing solely on the right edge of your lane can limit your overall visibility and may not be safe or necessary in this situation.

Answer:
While air is compressed in a piston cylinder there are following types of irreversibilities
1.Due to finite temperature difference heat transfer take place between cylinder and surrounding.
2.Due friction force between cylinder and piston .
3.Compression process is so fast due to this ,it leads in the irreversibility of system.
B. Determine the overall heat transfer coefficients, U; and U., for the pipe.
C. Would your answer change if the two materials were swapped so that the inside material were carbon steel and the outside material of the pipe were made of AISI 304 stainless steel? If so, calculate new values for UA and q. If not, explain why your answer would not change. (Here, assume the dimensions of the inner material (now plain carbon steel) match those of the AISI 304 schedule 30 stainless steel from part A, and the stainless steel is 0.075 inches thick on the outside.)
