A small town has a peak power requirement of 150 kW. A plant is created using the regenerative cycle. the energy can be extracted by pumping the working fluid deep into the ground and through long pipes. it was snown that by oversizing the enery extraction system, the temperature at the outlet is always 95 degrees celcius. the working fluid used is R-134a. cooling water from a local river is used to condense the R-134a. the temperature of the water is 10 degrees celcius. it is required that the quality of the turbine outlet is greater than 90%. also the isentropic efficiency for the turbine and all pumps may be assumed 85%. find the operating turbine pressure, condenser pressure, mass flow rate, number of feedwater heaters, cooling water flow rate and the motor size for driving the pumps.
