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.

Question

A 30-inch diameter steel pipe (ɛ = 0.00020 feet) delivers water from a reservoir into a hydroelectric turbine
and then empties into a river. The flow in the pipe is 100 cfs. The length of the pipe is 750 feet. The water
surface elevation in the reservoir is 300 feet above the water surface elevation in the river. The efficiency
of the turbine is 90%. Use the Darcy-Wiesbach equation to determine the friction head loss. Assume minor
losses are 20% of the friction head loss. The water temperature is 40°F. Determine the power generated
by the turbine in horsepower (hp) and in kilowatts (kW).

Assume that friction in the suction line is negligible. Toluene @ 35C is pumped from an open reservoir to a tank kept at a gauge pressure of 150 kPa. The pump itself is 3 m below the reservoir, while the discharge tank is 10m above the reservoir. While in the discharge line the friction head amounts to 7.5 m, determine the net positive suction head available for the pump. If the pump has an efficiency of 65%, determine the total power input. At the given temp, the density and vapor pressure of toluene are 862 kg/m3 and 40 mmHg.
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.
