9.5 An engine working on otto cycle has a volume of 0.45 m, pressure I bar and temparature 30c at the begining of compression stroke. At the end of compression, the pressure is 11 bar. 210 KJ of heat is added at constant volume. Determine: Pressures, lemparatures and volumes at salient points. in the cycle. (1) Efficiency. Pressure (1) Percentage clearence Effience (iv) Net work per cycle (v) Mean effective (vi) Ideal power devoloped by the engine if the number of working cycles per minute is 210. Assume the cycle is reversible.
