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.

For the closed feedwater heater below, feedwater enters state 3 at a pressure of 2000 psia and temperature of 420 °f at a rate of ix10 ibhr. the feedwat extracted steam enters state 1 at a pressure of 1000 psia and enthalpy of 1500 btu/lbm. the extracted er leaves at an enthalpy of 528.7 btu/lbm steam leaves as a saturated liquid. (16) a) determine the mass flow rate of the extraction steam used to heat the feedwater (10) b) determine the terminal temperature difference of the closed feedwater heater
