Need help with this engineering problem. Make sure you circle the answers. For each cycle determine: (a) the net power developed per unit mass of steam flowing for the Rankine and Carnot cycle, in kJ/kg. (b) the percent thermal efficiency for the Rankine and Carnot.
Q1. Sketch T-s diagram for Rankine cycle with clear label for the following condition: Condensate pressure = 100 kPa • Boiler pressure = 3 MPa • Inlet temperature to the turbine = 350°C Determine thermal efficiency of the cycle. ANSWER
Air enters the compressor of a gas turbine at a pressure of 100 kPa and a temperature of 300 K, where it is compressed to a temperature of 680 K. The pressure ratio of the cycle is 8. Before entering the turbine, there is a heat transfer of 950 kJ/kg to the air. Since the turbine's isentropic efficiency is 84 percent,a) Show the cycle in the T-s diagram.b) The ratio of the work required to operate the compressor to the work obtained from the turbine.c) Calculate the thermal efficiency.(Ignore the variation of specific heats for air with temperature)
