A regenerative gas-turbine power plant with two stages ofcompression and two stages of expansion operates on a Brayton cyclewith a pressure ratio across the two-stage compressor of 12. Airenters the first stage of the compressor at 100 kPa and 300 K. Atthe intercooler exit, the temperature is 300 K. In both turbinestages, air enters at 1400 K. The total heat transfer rate to theair in both combustors is 5,000 kW. The regenerator has anefficiency of 70%, both compressor stages have an isentropicefficiency of 75%, and both turbine stages have an isentropicefficiency of 80%. The pressure in the intercooler and reheater is600 kPa. Using an Air Standard Analysis, find the following
(a) Thermal Efficiency in Percentage
(b) net work output
(c) mass flow rate
(d) Intercooler/Reheater pressure that maximizes the cycle'sthermal efficiency
(e) Max Work output
