Question

A thermodynamic cycle uses 0.5 kg of air works in a three-process air-standard power cycle:
Process 1-2: Isothermal expansion
Process 2-3: Constant volume
Process 3-1: Isentropic, k=1.4
Given: Pressure and temperature at the end of constant volume process is P3=100 kPa and
T3=300K, respectively. If the isentropic compression ratio is 6.0, determine:
(a) The pressure, volume and temperature at each state points of the cycle.
(b) The heat added and rejected throughout the cycle, in kJ
(c) The work net output, in kJ
(d) The thermal efficiency.
(e) Illustrate the cycle in Pv and Ts coordinates.
(Ans. Q1-2=157.95 kJ, Q2-3=-112.93 kJ, Q3-1=0, 45 kJ, 28.5%)
