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 Maximum temperature is higher Combustion is at constant volume Expansion and compression are isentropic Heat rejection is lower Maximum temperature is higher Combustion is at constant volume Expansion and compression are isentropic ANSWER DOWNLOAD EXAMIANS APP
Engineering Thermodynamics A manufacturer claims to have a heat engine capable of developing 20 h.p. by receiving heat input of 400 kcal/mt and working between the temperature limits of 227° C and 27° C. His claim is Theoretically possible Cost will be very high Not possible May be possible with lot of sophistications Theoretically possible Cost will be very high Not possible May be possible with lot of sophistications ANSWER DOWNLOAD EXAMIANS APP
Engineering Thermodynamics An open system is one in which Mass does not cross boundaries of the system, though energy may do so Neither mass nor energy crosses the boundaries of the system Both energy and mass cross the boundaries of the system Mass crosses the boundary but not the energy Mass does not cross boundaries of the system, though energy may do so Neither mass nor energy crosses the boundaries of the system Both energy and mass cross the boundaries of the system Mass crosses the boundary but not the energy ANSWER DOWNLOAD EXAMIANS APP
