Water is boiled in a nuclear steam power plant by transferring heat from the reactor core. The water is to boil (change from a saturated liquid to a saturated vapor) at a temperature of 300°C. The reactor core is maintained at 900 K. If the rate at which the water is to boil is 15 kg/s, what is the rate of entropy change of the water, and what is the rate of entropy change of the reactor core? Is the process reversible? How does this compare to the process in Problem?
Problem
Water is boiled in a steam power plant by transferring heat from combustion gases. The water is to boil (change from a saturated liquid to a saturated vapor) at a temperature of 300°C. The combustion gases are supplied at a temperature of 1400 K. If the rate at which the water is to boil is 15 kg/s, what is the rate of entropy change of the water, and what is the rate of entropy change of the combustion gases? Is the process reversible?
