For the system-Water at 20°C flows by gravity through a smooth pipe fromone reservoir to a lower one. The elevation difference is 60 m.The pipe is 360 m long, with a diameter of 12 cm.  A pump, which delivers15,000 W to the water, is used at night to refill the upper reservoir. The pipe diameter is increased from 12 cm toprovide more flow. If the resultant flow rate is 90 m3/h, estimatethe new pipe size.

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.
