Asteam power plant operates on a simple nonideal rankine cycle between the pressure limits of the 10 mpa and 10 kpa in the boiler and condenser, respectively. due to the metallurgic limits in the fabrication of the turbine blades, the maximum temperature in the cycle is not to exceed 500oc. the isentropic efficiency is 85% for both the turbine and the pump. a)show the cycle on a t-s diagram with respect to saturation lines. b)solve for the rate of work done by the compressor on the steam flow. c)determine the rate of heat input and output in the boiler and condenser, respectively, when the power plant operates at its maximum capacity. d) determine the thermal efficiency of the cycle. e) what is the required mass flow rate of the steam through the cycle to generate 210 mw in the power plant?
