A power plant using a Rankine power generation cycle and steam operates at a temperature of 81.25°C in the condenser, a pressure of 5 MPa in the boiler and a maximum boiler temp of 775°C. The cycle operates at steady state with a mass flow rate of 2.5kg/s. Use the steam tables in the appendix of Sandler (p. 917 to 925). a.) Draw out the cycle, calculate the work required for the pump, the work output by the turbine, the heat into the boiler, and the heat out of the condenser. b.) What is the efficiency of this power plant? c.) If the turbine was only 89% efficient but still adiabatic (only generates 89% of the calculated work from part b), what is the overall efficiency of the cycle?

A geothermal resource/aquifer has been tested and confirmed to continuously produce saturated liquid water at 230°C. It is desired to construct a 60 MW geothermal power plant, which will utilize this resource. Two designs are proposed: a) a single flash unit and b) a dual-flash unit. A nearby cooling pond may supply sufficient cooling water to keep the condenser of the plant at 40°C. For the two types of units under consideration calculate: a) The total amount of steam that needs to be produced. b) The total amount of water the wells must provide. c) If each well produces 60 kg/s of water, what is the number of wells that must be drilled?
