3. The figure below shows a simple vapor power plant operating at steady state with water as the working fluid. Data at key locations are given on the figure. The mass flow rate of the water circulating through the components is 109 kg/s. Lost heat transfer and kinetic and potential energy effects can be ignored. Assuming a source temperature of 2400 K and a sink temperature of 300 K, (a) Show the process on P-v and T-s diagrams. (b) Determine the net power developed. (e) Determine the thermal efficiency. (d) The second-law efficiency of the refrigerator. (e) Determine the isentropic turbine efficiency. (f) Determine the isentropic pump efficiency. (g) Determine the mass flow rate of the cooling water. (h) Determine the irreversibility of each process and the total irreversibility.
