Water vapor enters a Lule with an input cross-sectional area of 0.02 m2 at a temperature of 1.8 MPa and 400C. Water vapor passes through the Lule with a flow of 5 kg/s, and in this process there is a heat loss of 2.8 kJ / kg from the Lule. If the pressure at the outlet is 1.4 MPa and the speed is 275 M/s, find the speed at which the water vapor enters the Lule and the temperature at the outlet of the Lule.

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.
