Water is the working fluid in a regenerative rankine cycle with one open feedwater heater. steam enters the turbine at 1800 lbf/in2 and 1200°f and expands to 120 lbf/in.2, where some of the steam is extracted and diverted to the open feedwater heater operating at 120 lbf/in.2 the remaining steam expands through the second-stage turbine to the condenser pressure of 2 lbf/in.2 each turbine stage and both pumps have isentropic efficiencies of 85%. flow through the condenser, open feedwater heater, and steam generator is at constant pressure. saturated liquid exits the open feedwater heater at 120 lbf/in.2 the mass flow rate of steam entering the first stage of the turbine is 2.36x106 lb/h. determine for the cycle
(a) the mass flow rate of steam entering the first stage of the turbine, in lb/h.
(b) the rate of heat transfer, in btu/h, to the working fluid passing through the steam generator, including the reheat section.
(c) the thermal efficiency.
