As water is flowing from a water tower to someone house, water is flowing at a speed of 3 m/s in a pipe with diameter of 0.3 m. The pipe gradually increases to a diameter of 1.8 m and then gradually decreases to a diameter of 1.1  m. Draw neat sketch. i) what is the speed of the water when it reaches the pipe diameter  of 1.1 m? ii) what is the flow rate of water flowing through the pipe in lit/hr?

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.
