The gases coming out of the steam boiler are discharged from a chimney with a rectangular area of 15x20 ft at a constant speed of 50 ft / s. The flue line is 250 ft long and there are 2 bends at 90 degrees. The temperature of the gases is constant at 180 F and an average pressure of 1 atm. Its physical properties are the same as the air in the same conditions. Calculate the pressure difference and required power in the flue line.

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.
