Engineering Thermodynamics For a perfect gas, according to Boyle’s law (where P = Absolute pressure, V = Volume and T = Absolute temperature) V/T = constant, if p is kept constant P v = constant, if T is kept constant T/P = constant, if v is kept constant P/T = constant, if v is kept constant V/T = constant, if p is kept constant P v = constant, if T is kept constant T/P = constant, if v is kept constant P/T = constant, if v is kept constant ANSWER DOWNLOAD EXAMIANS APP
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 working parts of the engine must be friction free The pressure and temperature of the working substance must not differ, appreciably, from those of the surroundings at any stage in the process All the processes, taking place in the cycle of operation, must be extremely slow All of these The working parts of the engine must be friction free The pressure and temperature of the working substance must not differ, appreciably, from those of the surroundings at any stage in the process ANSWER DOWNLOAD EXAMIANS APP
