10. An engine developing 30 brake horsepower must be cooled by a radiator through which water is pumped from the engine. Using the following factors: Heat transferred from engine to cooling water, expressed as horsepower, equals 40 HP. Water temperatures in radiator: Top water = 2000F. Bottom water = 1900F. Weight of 1 gallon of water = 8.33 lbs. Calculate the required rate of flow of water in gallons per minute. A. 15.4 gal/min B. 20.4 gal/min C. 123.4 gal/min D. 14.5 gal/min

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.
