(Note: you should not have to consider the behavior of the gas in part A at all for this calculation.) Find p 2A (kPa), T 2A (K), and S 2A-S 1A (kJ/K). Find Q 12 (kJ). (Hint: use the first law.) What is the change of S (kJ/K) for the universe? A B 2 A B 1 Recitation Problem 2. A simple Rankine cycle operates between a pressure of 40 bar and 0.1 bar. The isentropic efficiencies are 92% for the pump and 88% for the turbine. m = 1000 kg/sec Sketch the corresponding ideal cycle on a T-s diagram. Find W p , W t , Q in , Q out , , and BWR....
