An ideal combined Rankine cycle contains a reheat and a open feedwater heater, this is also referred to as a regenerative cycle. Steam enters the high pressure turbine at 500psi, 700F and is extracted to an open feedwater heater at 120 psi at saturated liquid. The rest of the steam is reheated to 700F at the constant pressure of 120psi and if fed to the lower pressure turbine. The condenser pressure is 2 psi. Calculate the thermal efficiency of the cycle and the net work per pound mass of steam.
