Engineering Thermodynamics The condition for the reversibility of a cycle is All the processes, taking place in the cycle of operation, must be extremely slow All of these The pressure and temperature of the working substance must not differ, appreciably, from those of the surroundings at any stage in the process The working parts of the engine must be friction free All the processes, taking place in the cycle of operation, must be extremely slow All of these The pressure and temperature of the working substance must not differ, appreciably, from those of the surroundings at any stage in the process The working parts of the engine must be friction free ANSWER DOWNLOAD EXAMIANS APP
Engineering Thermodynamics According to First law of thermodynamics, Total energy of a system remains constant Work-done by a system is equal to the heat transferred by the system Total internal energy of a system during a process remains constant Internal energy, enthalpy and entropy during a process remain constant Total energy of a system remains constant Work-done by a system is equal to the heat transferred by the system Total internal energy of a system during a process remains constant Internal energy, enthalpy and entropy during a process remain constant ANSWER DOWNLOAD EXAMIANS APP
