The expansion of the gases may be assumed to take place according to a reversible law, pv= constant, from 55 bar to 1.4 bar. The specific internal energy after expansion is 230 kJ/kg. Calculate the heat rejected to the cylinder cooling water per kilogram or gases during the expansion stroke.The worke done by the system is 465.96 kj/kg
