Engineering Thermodynamics Otto cycle efficiency is higher than Diesel cycle efficiency for the same compression ratio and heat input because in Otto cycle Heat rejection is lower Expansion and compression are isentropic Combustion is at constant volume Maximum temperature is higher Heat rejection is lower Expansion and compression are isentropic Combustion is at constant volume Maximum temperature is higher ANSWER DOWNLOAD EXAMIANS APP
Engineering Thermodynamics The work ratio of a gas turbine plant is given by (Net work output)/(Work-done by the turbine) (Net work output)/(Heat supplied) (Isentropic increase in temperature)/(Actual increase in temperature) (Actual temperature drop)/(Isentropic temperature drop) (Net work output)/(Work-done by the turbine) (Net work output)/(Heat supplied) (Isentropic increase in temperature)/(Actual increase in temperature) (Actual temperature drop)/(Isentropic temperature drop) ANSWER DOWNLOAD EXAMIANS APP
