a.Draw a schematic diagram with labels of states of a substance; b.For uniformity purposes, assign STATE 1 at the inlet of a high-pressure turbine. The states must be arranged in a chronological order; c.Plot each cycle in a t-s diagram with the states consistent to the states assignment in the schematic diagram; d.Show a detailed solution. Consider a regenerative vapor power cycle with a single open feedwater heater. Steam enters the first turbine stage at 12MPa, 500 0C, and expands to 0.3MPa where some steam is extracted and fed to the feedwater heater. The remainder expands through the second-stage turbine and exits at the condenser pressure of 0.01 MPa. Saturated liquid at 0.3 MPa leaves the open feedwater heater. If the net power output of the cycle is 100 MW,and the turbine stages and pumps are isentropic, determine (a) the thermal efficiency, and(b) the mass flow rate of steam entering the first turbine, in kg/h.
