An ideal gas-turbine cycle has two stages of expansion and two stages of compression. The pressure ratio is given as 8 to 1 for each turbine stage and each compressor stage. At the entrance to the first compressor, the pressure is 14 lbf/in2 and at the entering each compressor, temperature is 70 F, and at the entering each turbine, temperature is 2000 F. The cycle has also an ideal regenerator. Find a) the compressor work,  b) the turbine work,  c) the thermal efficiency of the cycle.

Question

An ideal gas-turbine cycle has two stages of expansion and two stages of compression. The pressure
ratio is given as 8 to 1 for each turbine stage and each compressor stage. At the entrance to the first
compressor, the pressure is 14 lbf/in2
and at the entering each compressor, temperature is 70 F, and at
the entering each turbine, temperature is 2000 F. The cycle has also an ideal regenerator. Find
a) the compressor work, 
b) the turbine work, 
c) the thermal efficiency of the cycle.
