For Air: k=1.4; Cp= 1.004 kJ/kg K; C = 0.717 kJ/kg; R=0.287 kJ/kg K For Helium: k= 1.66; Cp=5.1926 kJ/kg; C = 3.1156 kJ/kg; R=2.0769 kJ/kg K For Nitrogen: k=1.4; Cp=1.0398 kJ/kg; C = 0.743 kJ/kg; R=0.2968 kJ/kg K F.1 Consider a 210 MW steam power plant that operates on a simple Rankine cycle. Steam enters the turbine at 10 MPa and 500°C and is cooled in the condenser at a pressure of 10 kPa. - a) Show the cycle on a T-s diagram with respect to saturation lines. - b) Compute the thermal efficiency of the cycle. - c) Compute the mass flow rate of the steam. Thermal efficiency Mass flow rate of the steam F.2 Air is used as the working fluid in a simple ideal Brayton cycle that has a pressure ratio of 12, a compressor inlet temperature of 300 K, and a turbine inlet temperature of 1000 K. Determine the required mass flow rate of air for a net power output of 90 MW, assuming both the compressor and the turbine to be isentropic. Assume constant specific heats at room temperature.
