A closed gas turbine unit uses neon as the working fluid. There are two stages of compression with intercooling from 480kPa and 290K to a maximum pressure of 2.75MPa with an intermediate pressure of 1149kPa. The regenerator has an effectiveness of 60% and delivers the neon to the high-temperature heat exchanger, where it is heated to 890K. There are two turbine stages, the first discharging at 1170kPa. Following the first turbine stage, a heat exchanger re-heats the neon temperature to 890K. The second turbine exhausts at 480kPa to the regenerator. All the expansion and compression processes are isentropic and using constant specific heats at room temperature, determine:

a. The compressor work per kilogram
b. The turbine work per kilogram
c. The heat added to the cycle per kilogram
d. The thermal efficiency
e. The power output for a neon flow rate of 45kg/s
