Two students suggest different functions for the battery plays a flashlight.
Student A: "The battery supplies the charge which allows the light bulb to light. When the battery no longer works, it is because it has run out of charge."
Student B: "The battery pumps the charge around the circuit. The charge itself comes from the conducting elements of the circuit; the battery supplies the energy to pump this charge. When the battery no longer works, it is because the energy-producing chemicals have been consumed."
(a) Which student (A or B) do you agree with?

Atwo-stage air compressor operates at steady state, compression 10m^3/min of air from 100 kpa and 300k to 1200 kpa. an intercooler between the two stages cools the air to 300k at a constant pressure of 350 kpa. the compression processes are isentropic. a) calculate the power required to run the compressor, in kw b) compare the result to the power required for isentropic compression from the same inlet state to the same final pressure.
