Question:
A power plant burns coal to produce pressurized steam at 535 K. The steam then condenses back into water at a temperature of 323 K.
(a) What is the maximum possible efficiency of this plant?
(b) If the plant operates at 50.0% of its maximum efficiency and its power output is 1.23 × 108 W, at what rate must heat be removed by means of a cooling tower?
(c) During periods of low demand, the steam engine is used to pump water 380 m uphill from one reservoir to another. (Then during periods of high demand, the water is released to drive turbines and generate electricity.) What is the maximum possible rate (in m3/s) at which water can be pumped uphill?
