A brayton cycle with regeneration using air as the working fluid has a pressure ratio of 5. The minimum and maximum temperatures in the cycle are 360 and 1250 K. Assuming an isentropic efficiency of 80% for the compressor and 85% for the turbine, an effectiveness of 70% for the regenerator, a source temperature of 1200 K, an ambient temperature of 298 K. and an ambient pressure of 100 kPa, determine the following 1- The air temperature at the turbine exit 2- The net work output 3- The thermal efficiency

Question

A brayton cycle with regeneration using air as the working fluid has a pressure ratio of 5. The minimum and maximum temperatures in the cycle are 360 and 1250 K. Assuming an isentropic efficiency of 80% for the compressor and 85% for the turbine, an effectiveness of 70% for the regenerator, a source temperature of 1200 K, an ambient temperature of 298 K. and an ambient pressure of 100 kPa, determine the following

1- The air temperature at the turbine exit
2- The net work output
3- The thermal efficiency
4- The total energy destruction
5- The energy of the exhaust gases at the exit of the regenerator
