Steam enters the first stage turbine at 40 bar and 500C with a volumetric flow rate of 90 m^3/min. Steam exits the turbine at 20 bar and 400C. The steam is then reheated at a constant pressure to 500C before entering the second stage turbine. Steam leaves the second stage turbine as saturated vapor at 0.6 bar. For operation at steady state, and ignoring heat transfer out of the turbines, and kinetic and potential energy effects, find: (a) mass flow rate of the steam in kg/h, (b) total power produced by the first and second stage turbines, in kW and (c) rate of heat transfer to the steam flowing through the reheater, in kW. (note. the 2 turbines are coupled together)
