An ideal otto cycle has a compression ratio of 8. at the beginning of the compression process, air is at 100 kpa and 17°c, and 800 kj/kg of heat is transferred to air during the constant-volume heat-addition process. accounting for the variation of specific heats of air with temperature, determine (a) the maximum temperature and pressure that occur during the cycle, (b) the net work output, (c) the thermal efficiency, and (d) the mean effective pressure for the cycle. (e) also, determine the power output from the cycle,

(a) the maximum temperature and pressure that occur during the cycle are 1780.46K and 4911.58kPa respectively.

(b) the net work output is 451.78kJ/kg

(c) the thermal efficiency is 56.47%

(d) the mean effective pressure for the cycle is 86.011kPa

(e) power output from the cycle - there is no data to get this value since the speed (revolution per minute) of the engine is not given.

Explanation:

It is difficult to get type the calculation here but I have attached them in pages of 4.
