Apiston- cylinder assembly for a cold air-standard otto cycle has a bore of 3 in., a stroke of 7 in., and minimum volume of 15 in^3. the maximum temperature and pressure are 1500 degrees fahrenheit and 50 lbf/in^2 , with a heat addition of 200 btu/lbm. given cv=0.171 btu/lbm degrees rankine, r=53.33 ft lbf/lbm degree rankine and m= 28.97 lbm/lbmol, determine: a. compression ratio b. specific volume at the bottom dead center (ft^3/lbm). c. temperature at the end of compression ( degree rankine). d. pressure at the end of compression ( lbf/ft^2)
