A sample of an ideal gas goes through the process shown in Figure P20.32. From A to B, the pressure increases from 1 atmosphere to PB=3.06 atmospheres and the process is adiabatic; from B to C, it is isobaric with 335.16 kJ of energy entering the system by heat. From C to D, the process is isothermal; from D to A, it is isobaric with 361.77 kJ of energy leaving the system by heat.
How much heat enters the system along the isothermal path CD?How much work is done by the system after one complete cycle?What is the efficiency of the cycle?
What would be the efficiency of a Carnot engine operating between the temperature extremes of this cycle?
Determine the difference in internal energy, Eint, B - Eint, A.
