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.

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 = ?
A pipe line of length 2000 m is used for power transmission. If 110 kW power is to be transmitted through the pipe in which water having a pressure of 490.5 N/cm2at inlet is flowing. If the pressure drop over the length of pipe is 98.1 N/cm2and ff = 0.0065.Determine:The diameter of the pipe and the volume flow rate; and If a nozzle is introduced at the end of the pipe, what would be its diameter and the power transmitted.
The diagram shown illustrates the flow in a circular metal duct 20 feet long. The duct has a sudden contraction at the inlet and sudden expansion at the outlet. The diameter of the duct is 10 inches and the flow rate is 600 cfm. The duct is such that both ends have area ratio of 0.6. Thus A2/A1 = A3/A4 = 0.6. Calculate:(a) Pressure loss in the duct due to sudden contraction (in. wg.).
A centrifugal pump rotates at 1500 revolutions per minute to transport water with a bulk velocity of 1 m/s through a circular pipeline which has an internal diameter of 300 mm. The total head rise delivered by the pump is 25 m, and the total hydraulic head loss through the pump is 5 m. The impeller has an inner diameter of 120 mm, and the width of the inlet to the impeller is 60 mm. The circumferential area of the impeller inlet and outlet is reduced by 12% due to the effect of vane thickness, and the radial velocity through the impeller is constant. The vane outlet angle is 60° to the radial direction. The volumetric efficiency is 96%, the mechanical efficiency is 90%, and the reduction in theoretical head due to relative circulation is 29%. Assume no swirl at the inlet to the impeller.
The flow rate between tank A and tank B shown in the figure will decrease by 30% by adhering a second pipe that goes from point C to tank B. If the surface elevation of tank A is 25 ft higher than that of tank B, determine the diameter, D, of the second pipe. Despise lost minor and assume that the friction factor is 0.02.

Water at 20°C is pumped at a constant rate of 9 m3/h from a large reservoir resting on the floor to the open top of an experimental absorption tower. The point of discharge is 5 m above the floor, and friction losses in the 50-mm pipe from the reservoir to the tower amount to 2.5 J/kg.
