Use an otto cycle to analyze a six-cylinder, four-stroke internal combustion engine operating at 2600 revolutions per minute (rpm). the cycle operates with a bottom dead center pressure of 14.7 lbf/in and a temperature of 80 degrees f. the compression ratio is 12, and the maximum pressure achieved by the cycle is 1020 lbf/in2. if the cylinder volume is 0.0186 ft, calculate: 1. the engine power in horsepower (hp)2. the mean effective pressure3. the pressure required to maintain the same horsepower as (1) with a 10% smaller cylinder volume4. the engine power and mean effective pressure using a cold air-standard analysis with k = 1.4
