Question
A three process power cycle operating with 0.5 Kg/s of nitrogen as the
working substance operates in the following process:
Process 1-2: Constant temperature compression
T1 = 27°C, P, = 100KPA
Process 2-3: Constant volume heat addition
Process 3-1: Polytropic expansion (n=1.30)
The maximum pressure of the cycle is 300KPa and the isothermal
compression requires -74 KJ/Kg of work. Determine for the cycle:
a. The work net in KW
b. Show the cycle on T-S and P-V coordinate
