Each second, a nuclear power plant generates 2000 mj of thermal energy from nuclear reactions in the reactor's core. this energy is used to boil water and produce high-pressure steam at 300 degree c. the steam spins a turbine, which produces 700 mj of electric power, then the steam is condensed and the water is cooled to 30 degree c before starting the cycle again. a. what is the maximum possible efficiency of the plant? b. what is the plant's actual efficiency?

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.
