Question 2) A gas-turbine power plant operates on a gas-turbine cycle which has the pressure ratio of 6. At the compressor inlet and turbine inlet, the gas temperature values are 400 K and 1550 K, respectively. The compressor efficiency is 78% and the turbine efficiency is 87%. Considering, the air-standard assumptions, a) determine the isentropic exit temperature values of the compressor and turbine components, b) determine the real exit temperature values of the compressor and turbine components, c) Find the thermal efficiency of the gas-turbine power plant if a regenerator component having an effectiveness of 90% is used in the system (assume the conditions of steady operation along the system, consider the air-standard assumptions to be applicable, neglect the potential and kinetic energy changes and their calculations, and the variation of specific heats with temperature has to be considered, hint: Linear interpolations are required in this question).
