In an ideal constant pressure cycle is the one in which both QA as well as QRare at constant pressure using air the overall volume ratio of the cycle is 81 Adiabatic compression begins at

In an ideal constant pressure cycle, ( is the one in which both, QA as well as QRare at constant pressure ) using air, the overall volume ratio of the cycle is 8:1. Adiabatic compression begins at 2/7th of the compression stroke when the conditions of the air are 100kN/m2, 0.084m3 and 28oC. If g=1.4 and cp=1.006 kJ/kg.K,

Determine:

a) The pressure, volume and temperature at the state point of the cycle;

b) The heat received/cycle

c) The work done/cycle

d) The thermal efficiency of the cycle
