Steam enters a mixing chamber at 100 kPa, V1= 40 m/s, and a specific volume of 0.4 m3/kg. Liquid water, at 100 kPa and 25 ∘C, enters the chamber through a separate duct with a flow rate of m˙=55 kg/s and a velocity of 1 m/s. If liquid water leaves the chamber at 100 kPa, T2=50 ∘C, 5.41 m/s, and a volumetric flow rate of 3.355 m3/min, determine the port areas at the inlets and outlet. Assume liquid water density to be 1000 kg/m3 and steady state operation. Express your answer to three significant figures in cm2

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.
