2. A Steam power plant uses a Rankine cycle to produce electrical power. The boiler pressure is 2 MPa and the temperature at the turbine inlet is 300C. The pump inlet pressure is 0.025 MPa and the entropy is 0.8931 kJ/kg-k. The turbine gives 1MW of work to the generator. Find the dryness of the steam at turbine exit, Wp, Qa, Qr, Wt, Wnet, efficiency, SR, and mass flow rate of steam.
