1) A supply of geothermal hot water is used as the energy source in an ideal Rankine cycle with R-134a and shown in the attached figure. Saturated R-134a leaves the boiler at 85°C and the condenser temperature is 40°C. Calculate the thermal efficiency of the cycle.

efficiency=(T1-T2)/T1=(85-40)/85=53%
