A certain engine work on an air standard dual cycle has a compression ratio of 14 and compression begin at 0.6 bar and 120 The maximum pressure is 25 bar. The heat supplied to air at constant pressure is 1/4 of the heat supplied at a constant volume. Find the following: (a) The cycle efficiency, (b) The mean effective pressure in bar. For air take C 0.718 kg K, C 1.005 k/kg. K and R-287 /kg. K
