A horizontal pipe of diameter 0.2 m is suddenly enlarged to  0.3 m. If the rate of flow of water through the pipe is 0.2  m3/s and the intensity of pressure in the smaller pipe is 100  kPa, then find (i) the head loss due to sudden enlargement,  (ii) power loss due to enlargement and (iii) intensity of  pressure in the larger diameter pipe.

Fluid Dynamics

The study of the flow of gases and liquids, usually in and around solid surfaces, is known as fluid dynamics in physics and engineering. Fluid dynamics, for example, can be used to evaluate the movement of air through an airplane wing or the surface of a vehicle. It can also be used in ship design to increase the speed at which ships pass through water.
