Just want to compare against my answers


Extracted text: DIctate Select Styles Editing Voice Ed Part II: Power Cycles & Fluid 3. Assume an Otto cycle with compression ratio of CR = 9 1. The intake air is at 100kPa, 20°C, and the volume of the chamber is 500cm prior to the compression stroke. The temperature at the end of the adiabatic expansion is T. = 800K. If air specific heat capacity at constant pressure of air at atmospheric pressure and room temperature is c 1.01KJ/kgK Specific heat capacity at constant volume of air at atmospheric pressure and room temperature: Cv = 0.718KJ/kgK Calculate: (i) the mass of the intake air (ii) the temperature T3; (iii) the pressure Pai (iv) the amount of heat added by burning fuel-air mixture; (v) the thermal efficiency of the cycle; (vi) the mean effective pressure (MEP).
