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.

Question

The inlet of a centrifugal pump is 7 ft above a water surface level. The reentrant inlet (KIN = 1)
includes 12 ft of 2 in. pipe (k, = 0.0002 ft) and contains one long sweep elbow (Kel = 0.41). The 2 in.
outlet line discharges to the atmosphere and contains two long sweep elbows and one check valve
(Kcv = 2.1) in its 200 ft length. The discharge is 20 ft above the original water surface. Given the
attached pump curve, determine the flow of water at 70°F (u = 1.059 x 10-5 ft²/s).

Question 2) The centrifugal pump in the figure is in his preference Passing water at 25°C from the tank through the 1.22 m exchange store pumping. Inner diameter of the suction channel is 101.6 mm, in total it is 0.0306 and its length is 3.2 m. It the local coefficients of the user in the pipe are 7.4. If the pump works at a flow rate of 109 m3/h ENPY=1.52 is m. Does the pump work without cavitation at this flow? Show the calculation. For water, p=997 kg/m3 and Pb=3.169 kPa.

Problem 2 A pump is needed in a water supply system. The water is being pumped out of a ground-level storage reservoir with water surface elevation of 149.27 ft and needs to pass over a hill 2 miles away, where the pipe centerline is at elevation 200.00 ft. The flowrate is 22 mgd, pipe diameter is 24 inches, Hazen-Williams friction factor is 110, and pressure at the crest of the hill must be at least 20 psi. (a) What head must the pump provide? (b) How much power will be added to the water? (c) What size motor should be purchased if the pump/motor combination has an efficiency of 80 percent?
