Steam expands steadily in a turbine at a rate of 40,000 kg/h from 8 MPa and 500°C to a saturated vapor at 40 kPa. A) Represent the process on a T-s diagram when the turbine operates under the given conditions in an adiabatic and irreversible manner, and also when it operates in an adiabatic reversible manner between the same pressures. Use the same T-s diagram for both processes. P₁ = 8 MPa T₁ = 500 °C 40,000 kg/hr Steam Turbine

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.
