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 Maximum temperature is higher Combustion is at constant volume Heat rejection is lower Expansion and compression are isentropic Maximum temperature is higher Combustion is at constant volume ANSWER DOWNLOAD EXAMIANS APP
Engineering Thermodynamics Zeroth law of thermodynamics Deals with conversion of mass and energy Deals with reversibility and irreversibility of process States that if two systems are both in equilibrium with a third system, they are in thermal equilibrium with each other Deals with heat engines Deals with conversion of mass and energy Deals with reversibility and irreversibility of process States that if two systems are both in equilibrium with a third system, they are in thermal equilibrium with each other Deals with heat engines ANSWER DOWNLOAD EXAMIANS APP
Engineering Thermodynamics An open system is one in which Both energy and mass cross the boundaries of the system Neither mass nor energy crosses the boundaries of the system Mass does not cross boundaries of the system, though energy may do so Mass crosses the boundary but not the energy Both energy and mass cross the boundaries of the system Neither mass nor energy crosses the boundaries of the system Mass does not cross boundaries of the system, though energy may do so Mass crosses the boundary but not the energy ANSWER DOWNLOAD EXAMIANS APP
Engineering Thermodynamics A path 1-2-3 is given. A system absorbs 100 kJ as heat and does 60 kJ of work while along the path 1-4-3, it does 20 kJ of work. The heat absorbed during the cycle 1-4-3 is +60 kJ -80 kJ -40 kJ -140 kJ +60 kJ -80 kJ -40 kJ -140 kJ ANSWER DOWNLOAD EXAMIANS APP
