In a steady state process, air enters a diffuser at 40°C and 150 kPa with a velocity of 170 m/s. For the exit velocity of 20 m/s, use constant specific heats approach and assume the process is reversible and adiabatic, determine • exit temperature of air in K: • exit pressure of air in kPa: 294.1|| 300.1 || 315.7 || 327.3|| 335.1| 340.9 || 352.4 132.3| 141.2|| 161.4|| 175.2|| 194.5|| 205.1|217.3

Work and Heat Transfer

It is generally related to thermal engineering which tells about the use, creation, conversion and transfer of heat energy between the systems. It is also considered that to transfer heat from one source to another, transfer of masses is also required. There are various mechanisms by which, transfer of heat takes place i.e. thermal conduction, convection, radiation or by change of phase. All these mechanisms have their own specific features which sometimes occur simultaneously within the same system.
