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.

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?

Find the value of Darcy friction factor.
I need help on this question: According to the question: a) If the pipe connected to the pump inlet has a diameter of 24 mm with length (LCP) of 5 m and Darcy friction factor of 0.03, what would be the actual head rise across the pump for a case where the pump outlet pressure is 200 kPa? The difference in height between pump inlet and outlet is 0.25 m, the tank exit is sharp-edged, and the water level in the tank to the tank exit pipe (HWL) is 2 m. Also, consider that the flow velocity inside the tank is negligible. The value of the actual head rise across the pump is = ? b) What would be the pump motor power if the efficiency is 60%? The value of the pump motor power is = ?

Water is transported by gravity through a 10-cmdiameter 550-m-long plastic pipe with an elevation gradient of 0.01 (i.e., an elevation drop of 1 m per 100 m of pipe length). Taking ? = 1000 kg/m3 and ? = 1 × 10−6 m2/s for water, determine the flow rate of water through the pipe. If the pipe were horizontal, what would the power requirements be to maintain the same flow rate?
