Concept explainers

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.

PLease include a diagram.A Special oil is to be used in an absorption tower. The preliminary design of the unit requires the oil to be pumped from an open tank with a 10 ft liquid level above the floor and forced through 150 ft of 3 inches schedule 40 pipe with a ball check valve and 5 elbows into the top of a tower 30ft above the floor. The operating pressure in the tower is to be 52 psig and the oil requirement is estimated at 50gpm. The viscosity of the oil is 15cP and its density is 53.5 lbm/ft3. Assuming the pumping outfit operates with an overall efficiency of 60%, what horsepower input will be required for the pump motor?
