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.

1 and 2 water (r = 1005 kg / m3, m = 1.807´10-3 kg / m × s) are connected by 40 m long 2 cm long plastic pipes. Losses next to losses in the piping system may be the cause of their losses.

Pum 2 cm I.D. Ball Valve Patm Problem 2: The drain on a large tank of liquid consists of a ball valve with a 2 cm inside diameter that connects to the tank with a well-rounded flow entrance. The height of the fluid surface above the valve entrance is denoted h. The pressure in the air space above the surface of the fluid is the same as that outside of the tank, Patm. Taking the losses to come solely from the ball valve and its entrance region, perform the following analysis: a. Find the velocity of the flow through the valve and the flow rate (in liters/sec) when h = 6 meters and the valve is fully open. b. Find the increase in fluid height h required to maintain the same flow rate as that found in Part a. with the ball valve 1/3 closed. c. How does the change in fluid height in Part b. compare with the increase in head loss caused by the partial closing of the valve?
