Asteam power plant operates on a simple nonideal rankine cycle between the specified pressure limits. the thermal efficiency of the cycle, the mass flow rate of the steam, and the temperature rise of the cooling water are to be determined. given: g1: wnet - 45 mw g2: p3-7 mpa 63: t3=500°c g4: pe=10 kpa g5: cooling water = 2000 kg/s g6: = ==87% determine: d1: t-s diagram d2: thermal efficiency of the cycle d3: mass flow rate of the steam d4: temperature rise of the cooling water
