At the beginning of the compression stroke an ideal otto cycle has an ideal pressure of 15 psia. A temperature of 75degF and specific volume of 13.2ft^3/lbm. At the end of compression, the specific volume is 1.76ft^3/lbm. The heat supplied to the cycle is 532BTU/lbm. For the cycle calculate. 1. Compression ratio2. The highest temperature of the cycle. (Rankine) 3. The highest pressure of the cycle. (psia) 4. The temperature at the end of the expansion of the air. (Rankine)5. The pressure at the end lf the expansion of thr air. (psia) 6. Heat rejected. (7. The net work of the cycle. 8. The thermal efficiency of the cycle. 9. The power developed by an ideal engine operating on this cycle using 0.5lb of air per second. (Horse Power)

IC engines

The term "engine" indicates a mechanical device/machine used to convert input energy to a specific mechanical output. The input energy may be in the form of chemical energy, thermal energy, or so on and mechanical output is in the form of mechanical energy (work done). Generally, the engines classify into two groups which are internal combustion type and external combustion type, and further, these two types can be classified into two types that are reciprocating and rotary engines.
