Transfer of heat through flowing material

The transfer of heat through flowing material is called CONVECTION.

Convection is one of the methods of heat transfer, the other two methods are conduction and radiation. Convection refers to the process through which heat is transported by mean of a heated fluid. Examples of fluid are water and air. When water is heated, it becomes less dense and rise as a result of increase in its buoyancy; as the heated water rise and moves up, it is immediately displaced by cold water. This set up a circulation motion in the water until all the water is evenly heated. The rising movement of the water carries energy with it. Fluids normally flow from a region of high temperature to the region of low temperature.

answer: a tank of height h is filled with water and sits on the ground. water squirts from a hole at a height y above the ground and has a range r. for two y values, 0 and h, r is zero. determine the value of y for which the range will be a maximum.
