# A supply of geothermal hot water is to be used as the energy

Rankine Cycle Problem. See attached file for full problem description.

A supply of geothermal hot water is to be used as the energy source in an ideal Rankine cycle, with R-134a as the cycle working fluid. (See the diagrams below) Saturated vapor R-134a leaves the boiler at a temperature of 85Â°C, and the condenser temperature is 40Â°C. Calculate the heat transfers in kJ/kg at the boiler and condenser.

Calculate the work in kJ/kg at the pump and turbine thermal efficiency of this cycle
