The hot reservoir for a Carnot engine has a temperature of 943 K, while the cold reservoir has a temperature of 442 K. The heat inputfor this engine is 5950 J. The 442-K reservoir also serves as the hot reservoir for a second Carnot engine. This second engine uses therejected heat of the first engine as input and extracts additional work from it. The rejected heat from the second engine goes into areservoir that has a temperature of 301 K.

Problem 2: This problem compares the energy output and heat transfer to the environment by two different types of nuclear power stations—one with the normal efficiency of 36 %, and another with an improved efficiency of 47 %. Suppose both have the same heat transfer into the engine in one day, 2.5 × 1014 J Part (a) How much more electrical energy is produced by the more efficient power station? Part (b) What is the change in the heat transfer to the environment after the upgrade to the more efficient power station?
A steam boiler has a total volume of 4 m3. The boiler initially contains 3 m3 of liquid water and 1 m3 of equilibrium steam at 0.1 MPa. The boiler is turned on and heat is transmitted to the water and steam. Meanwhile, the inlet and outlet valves of the boiler remain closed. The safety valve escapes when the pressure reaches 5 MPa. How much heat is transmitted to the water and steam before I open the safety valve?
A high temperature reservoir losing heat and hence entropy is a reversible process. A low temperature reservoir gaining a certain amount of heat and hence entropy is a reversible process. But a high temperature reservoir losing heat to a low temperature reservoir is irreversible. Why?
