Thirty-six grams of air in a piston–cylinder assembly undergo a stirling cycle with a compression ratio of 7.5. at the beginning of the isothermal compression, the pressure and volume are 1 bar and 0.03 m3, respectively. the temperature during the isothermal expansion is 1400 k. assuming the ideal gas model and ignoring kinetic and potential energy effects, determine: (a) the net work, in kj. (b) the percent thermal efficiency. (c) the mean effective pressure, in bar.
