Applied Fluid Mechanics

A fluid is a substance that is continuously deformed by the application of shear stress. The rate of deformation of a fluid depends on its viscosity. The fluid tries to flow when it interacts with some other system.

A centrifugal pump is used to pump water between two reservoirs as shown in the bellow figure. The dimensions and minor loss coefficients are provided in the figure. The pump rotates at 1600 rpm, the water inters the impeller normal to the blades and exits at an angle of 45° from radial. The inlet radius is 5.5-in, at which the blade width is 7.09-in. The outlet radius is 8.66-in, at which the blade width is 6.7-in. The volume flow rate is 23-cfm. Assuming 100 percent efficiency, calculate the net head produced by this pump in cm of water column height, the required brake horsepower in W and calculate the pump capability to pump water to upper reservoir.

A reaction turbine has guide vanes at an angle of 30° and the runner blades make an angle of 80° relative to the tangent at inlet. The blades width at the inlet is 4 of the outer diameter. The water does not have any tangential velocity at the outlet. The head is 25 m and the rotational speed of the runner is 16.67 rotations per second. The turbine efficiency is 88 %. Determine the turbine runner diameter at the inlet and the power developed. T
The system in Fig 2 pumps water from a lower reservoir to a higher reservoir. The pipe diameter is 0.235 m and the pipe lengths are L1= 5 m, L2= 4.5 m, L3= 1.5 m, and L4= 0.6 m. The impeller of the centrifugal pump has a diameter of 0.55 m and operates at 850 rpm. The uniform blade height is 51 mm. The water enters the pump parallel to the pump shaft with a flow rate of 0.16 m3/s. Take viscosity as 0.00112 N s/m2. Fig Q2: Piping system to pump water between two tanks. Work to 4 significant digits. Enter all values using base units or their combinations, i.e. m, m/s, Pa, N. Do not use multiples as e.g. mm, kPa. You can use values with exponents, such as 0.12e3. a) What would be the shaft power required to turn the impeller if the exit blade angle is 31 degrees. b)
In order to meet the stated goal of delivering 4 gallons per minute at a height of 670 meters, a single pump must have a maximum flow rate of 40 gpm. How many stages are needed if the speed cannot exceed 1352 rpm?
Problem-3: A centrifugal pump lifts water against a static head Az = EN m. The pipe setup has a constant diameter of 0.08 m, major losses in the suction side h, = EN3 m and in the discharge side hLD is 3 m. The pump impeller has a diameter of 0.15 m, exit width of 0.015 m, exit blade angle of 22° and speed of N = 20EN rpm. The hydraulic efficiency is 0.85. If the flow at the entrance is radial, find the discharge, pump head, atmospheric pressure Pat, Vapor pressure P, and maximum allowable height of the pump from the feeding tank water surface elevation if the pump is operating under T 25 °C at altitude H= 20EN m. %3D 0, = NPSHR/Hp =1.21×10³N = (P EN=62 Is-mx at-abs-P,)/Y-hLsT -0H, Pa-abs /Y = 10.33(1– 2.256x10-H)56 P,ly = e14.29-3985(T+233.4))
2. A pump is required to draw 50 of water from reservoir A, with static suction lift of 4.5 m to reservoir B, with static discharge head of 15 m. The pipe in the suction line is 6 in nominal diameter and 8 m long. The pipe in the discharge side is 4 in nominal diameter and 15 m long. The fittings and valves installed in the suction line are: one foot valve, one standard elbow and one gate valve; and in the discharge line are: one check valve, one gate valve, two standard elbows. Assuming an absolute roughness of 0.24 mm for a cast iron pipe, and an absolute viscosity of water of 0.01002 poise, and neglecting the head loss in the foot valve and at the exit in the discharge reservoir, determine the pump brake power if the pump efficiency is 82%. Draw the piping system.
The fluid flow rate was 1 m3 / s and the head was 10 m in the experiment performed at 2000 rev/min by water with the 1/4 ratio model of a centrifugal pump designed to be used for oil. Calculate the power given by the pump to the fluid when the prototype pump operates at 1000 rev/min (ρ water = 1000 kg / m3, ρ oil = 800 kg / m3)

The outlet blade angle is ß2 = 28°. Determine: 1. The flow rate of the pump. 2. The output power of the two stage centrifugal pump. p = 1000kg/m³ g = 9.81 m²/s Take
