Water flows at a velocity of 4.2 m/s from one reservoir (z = 41.5 m) to another reservoir (z = 8.0 m) over a 1011-m long, 300-mm diameter pipeline. If the total head loss is 19 times the velocity head, determine the power (in N-m/s) extracted by a turbine (z = 8.0 m) located between the reservoirs. Assume γ = 9790 N/m3.

Select one:

a. 4.772e4

b. 8.555e4

c. 6.075e4

d. 8.224e4

A pump is used to deliver water from a large reservoir to another large reservoir that is 20 m higher. The inlet of the pipe is submerged in the one reservoir and the exit is just above the surface of the other reservoir. If the friction head loss in the 200-mm-diameter, 4-km-long pipeline is 2.5 m for every 500 m of pipe length, determine the required power output of the pump so the flow is 0.6 m3/s.

Water (ρ = 999 kg/m3, μ = 1.3x10-3 N/s) from a large tank with P1 flows through a pipeline at the rate of 0.14 m3/s to atmosphere as shown. The pipe diameter of the entire piping system is 20 cm and material is cast iron. Knowing discharge velocity V2 is the same as the flow velocity in the pipe, no discharging nozzle loss, Kinlet = 0.5, and Kelbow = 1.1, calculate the absolute P1 (MPa) in the tank needed to...

A discharge of 2.8 m3 /s flows through a hydraulic turbine. On the 1 m inlet pipe at elevation 43.5 m, a pressure gage reads 345 kPa. On the 1.5 m discharge pipe at elevation 39, a vacuum gage reads 150 mm of mercury. If the total head lost through pipes and turbines between elevation 43.5 and 39 is 9 m, what power may be expected from the machine?
