2. Rankine Cycle. Consider a steam power plant operating on the simple ideal Rankine cycle. Steam enters the turbine at 5 MPa and 300°C.The wet mixture leaves the turbine at 50 kPa and a quality of 95%. Determine (a) the enthalpies at the start/end of each process, (b) the efficiency of this cycle, and (c) the efficiency of the Rankine engine. Thermal Efficiency Engine Efficiency h3 - h4 Ne hz - hị Wnet h4 - h, = 1- lout = 1- qin Nth qin h3 – h2 hz = h, + v;(P2 - P.) h4 = h, + x(hsg)
