An ideal otto cycle has a compression ratio of 8. at the beginning of the compression process, air is at 95 kpa and 27 c, and 750 kj/kg of heat is transferred to the air during the constant-volume heat-addition process. taking into account the variation of specific heats with temperature, determine
(a) the pressure and temperature at the end of the heataddition process
(b) the net work output
(c) the thermal efficiency
(d) the mean effective pressure for the cycle.
approximate answers:
(a) 4000 kpa 1500 k
(b) 400 kj/kg
(c) 50 percent
(d) 500 kpa.
