Problem 2: Win High-pressure liquid water (Pump Boiler Condenser à out Low-pressure liquid water FIGURE 7-1 Example of a power cycle. High-pressure steam 3 Turbine Wout Low-pressure superheated vapor or high-quality two-phase mixture A simple steam power cycle consists of a boiler, turbine, condenser, and pump as shown in the sketch above. All the heat removal in the cycle is done by the condenser which transfers the heat to pipes carrying cooling water. The cooling water has a mass flow rate of 7 kg/sec, and a specific heat of 4,180 J/kg-°C. The cooling water is supplied at a temperature of 10 °C and exits at 20 °C. Heat is supplied to the cycle through a steam boiler at a rate, Ċin = 420 kW. Find the following: a. The rate at which heat is rejected from the cycle to the cooling water, Qout- b.

A reheat cycle with two stages of reheating is executed with steam expanding initially from 20 MPa and 540C. The two reheater pressures are 3.8 MPa and 0.97 MPa, and the steam leaves each reheater at 540C. Condensation occurs at 60C. Compute the efficiency of the cycle.
