Consider a solar-pond power plant that operates on a simple ideal rankine cycle withrefrigerant-134a as the working fluid. the refrigerant enters the turbine as a saturated vaporat 1.4 mpa and leaves at 0.7 mpa. the mass flow rate of the refrigerant is 3 kg/s. show the cycle on a t-s diagram with respect to saturation lines, and determine

(a) the thermalefficiency of the cycle and

(b) the power output of this plant.
