Determine the air standard efficiency, Mechanical Engineering

Assignment Help:

Compare the efficiency of Diesel, otto and Dual combustion cycle on the basis of same compression ratio and same heat input. In an otto cycle air at 17oc and 1 bar is compressed adiabatically until the pressure is 15 bar. Heat is added at constant volume until pressure rises to 40 bar. Determine the air standard efficiency, the mean effective pressure and compression ratio for the cycle. Consideer Cv = 0.717 KJ/KgK and R = 0.8314 KJ/KmolK.
