1. The problem statement, all variables and given/known data: At the beginning of the compression stroke of a two-cylinder internal combustion engine the air is at a pressure of 101.325 kPa. Compression redeuces the volume to 1/5 of its original volume, and the law of compression is given by PV^1.2 = const. If the bore and stroke of each cylinder is 0.15 m and 0.25 m , respectively, determine the power absorbed in kW by compression strokes when the engine speed is such that each cylinder undergoes 500 compression strokes per minute. The answer is given as : 17.95 kW 2. Relevant equations : I hv written all formulas in the solution (attachment). 3. The attempt at a solution: I hv attached the solution I hv done. Please rectify my mistake... where I am doing wrong..my ans is not matching with the given one.
