A locomotive runs on a steam engine with a power output of 4.5 x 10
^{6}
W and an efficiency of 12 percent.
(a) Calculate the rate at which heat is being delivered to the steam engine.
(b) Calculate the magnitude of the resistive forces acting on the locomotive when it is moving with a constant speed of 7.0 m/sec.
Suppose the gas in another heat engine follows the simplified path ABCDA in the PV diagram below at a rate of 4 cycles per second.
(c) i. What does the area bounded by path ABCDA represent?
(c) ii. Calculate the power output of the engine.
(d) Indicate below all of the processes during which heat is added to the gas in the heat engine.
