A farmer is to pump water at 70'F from a river to a water storage tank nearby using a 125-ft-long, 5-in-diameter plastic pipe with three flanged 90 smooth bends. The water velocity near the river surface is 6 ft/s, and the pipe inlet is placed in the river normal to the flow direction of water to take advantage of the dynamic pressure. The elevation difference between the river and the free surface of the tank is 12 ft. For a...
Water (density 998 kg/m', absolute viscosity 1.12x10 Ns/m2) is pumped from a lake into a reservoir at a rate of 0.7 m/s. The water flows through a re-entrant opening, a valve, and a sharp-edge...
Water (density 998 kg/m', absolute viscosity 1.12x10 Ns/m2) is pumped from a lake into a reservoir at a rate of 0.7 m/s. The water flows through a re-entrant opening, a valve, and a sharp-edged exit, which have loss coefficients of 0.8, 10, and 1, respectively. The pipe has an absolute roughness of 1x104m and di of 0.30 m. The pump efficiency is 65%. A) Is the flow in the pipe laminar or turbulent? (2 points) B) What is the power...

11. Water is pumped from a reservoir at a lower elevation to an elevated reservoir by using a suitable pump. The lower reservoir water level have an atmospheric pressure head of I and is at an elevation of 20 ft. while the intake/suction side of the pump is at an elevation of 25 ft. The water is pumped at a rate of 425 gpm in a 6" diameter pipe, friction factor () is 0.017 and the length of pipe is...

5. Liquid ethanol is pumped from a large storage tank through a 1-inch ID pipe at a rate of 3.00 gal/min. (a) At what rate in (i) ft lbels and (ii) hp is kinetic energy being transported by the ethanol in the pipe? (b) The electrical power input to the pump transporting the ethanol must be greater than the amount you calculated in Part (a). What would you guess becomes of the additional energy? (There are several possible answers.)

Assume that the pipe size from the tank to the centrifugal pump is reduced to 0.5 inch. How would it affect the suction side pressure and operation of the pump? Just need help with the theory. I believe I need Bernoulli's equation.

A pipe leads from a storage tank on the roof of a building to the ground floor. The absolute pressure of the water in the storage tank where it connects to the pipe is 3.0×105Pa, the pipe has a radius of 1.0 cm where it connects to the storage tank, and the speed of flow in this pipe is 1.6 m/s. The pipe on the ground floor has a radius of 0.50 cm and is 9.0 m below the storage...
