15.6 A steam power plant operates on the Rankine cycle, with steam leaving the boiler at 6.0 MPa and 500°C. The plant supervisor wants to know the effect of back pressure (condensing pressure) on the cycle efficiency. (a) Determine and graph the cycle effi- ciency for back pressures of 7, 15, 30, 45, and 70 kPa. (b) Discuss the results in terms of available energy.
