In an Otto cycle, the compression ratio is 10 . The temperature at the beginning of compression and at the end of heat supply is 300 and \(1600 \mathrm{~K}\), respectively. Assume, \(\gamma=1.4\) and CV \(=0.717 \mathrm{KJ} / \mathrm{kgK}\). Find: (i) Heat supplied, and (ii) Efficiency of the cycle.
