An ideal otto cycle has a compression process ratio of 10, and a maximum volume of 0.4l. at the beginning of he compression process, the air is at 100 kpa and 40oc, and the maximum temperature in the cycle is 2100 k. assuming variable specific heats for air, determine: (a) the amount of heat supplied per cylinder, (b) the thermal efficiency, and (c) the number of revolutions per minute required for a net power output of 11 kw.
