limited gradient

Since a velocity gradient exists across the tube, the mean velocity of the liquid is to be considered. The viscous drag which comes into play when the liquid is in motion, is not taken into account. In above conservation principle, part of K.E. is converted into heat..

It is the movement of water between aquatic systems, air and land water vapour condenses to form clouds, and eventually rainfall. Plants play an important role in this cycle by the process of transpiration. The upper limit (maximum) of water availability of a soil is called field capac..

Climatic Factors - Temperature - Temperature is one of the essential and changeable environmental factors. It penetrates into every region of the biosphere and profoundly influences all forms of life by increasing or decreasing some of the vital activities of the organism. It is frequently a l..

. The kinetic energy and potential energy associated with the random motion constitute the internal energy. When a body sliding on a surface comes to rest due to friction, the organized motion of the body is converted to random motion of molecules in the body and on the surface. Since we cannot con..
