Question 2 (Gas power cycles) An ideal air-standard Otto cycle having a compression ratio of 9:1 uses air as the working fluid. The initial pressure is given as 95 kPa, at a temperature of 17 °C and a volume of 3.8 litres. During the heat addition process, 7.5 kJ of heat is added. 2.1 state 5 air-standard assumptions in gas power cycles, and (5) 2.2 draw the P-v and T-s diagrams for the cycle, determine (2) 2.3 all the points of the above cycle and the thermal efficiency (18) 2.4 the back work ratio (2) 2.5 the mean effective pressure (4) [31]
