1. A power plant working on an ideal Brayton cycle has a pressure ratio of 8. The gas temperature is 310 K at the compressor inlet and 1140 K at the turbine inlet Utilising the air-standard assumptions and accounting for the variation of specific heats with temperature: (a) Determine the specific enthalpies at each stage in the cycle. (b) Calculate the work input at the compressor and the work output at the turbine. (c) Calculate the heat supplied at the combustion chamber. (d) Calculate the thermal efficiency.
