Document Summary
When a pump draws 220 m3/h of water at 20 c from the reservoir, the total friction head loss is. 5 m. the flow discharges through a nozzle to the atmosphere. Estimate the pump power (in kw) delivered to the water. A hydroelectric turbine passes 8 million gal/min across a head of 600 feet. A long water trough of triangular cross section is formed from two planks. A gap of 0. 1 inch remains at the junction of the two planks. Water flows from a faucet on the first floor of a building with a maximum velocity of 20 ft/s. For steady inviscid flow, determine the maximum water velocity from the basement faucet and from the faucet on the second floor (assume each floor is 12 ft tall). In a laminar pipe flow that is fully developed, the axial velocity profile is parabolic as given by, u u. And as is illustrated in the figure below.
