A steam power plant operates on an ideal reheat-regenerative Rankine cycle with one reheater and two open feed water heaters. Steam enters the high-pressure turbine at 1,500 psia and 1,100 degrees Farenheit and leaves the low-pressure turbine at 1 psia. Steam is extracted from the turbine at 250 and 40 psia, and it is reheated to 1,000 degrees Farenheit at a pressure of 140 psia. Water leaves both feed water heaters as a saturated liquid. Heat is transferred to the steam in the boiler at a rate of 4 x 10^5 Btu/s. Determine (a) the mass flow rate of steam through the boiler, (b) the net power output of the plant, and (c) the thermal efficiency of the cycle.
