A 140 m long pipeline runs between two reservoirs, both ends being under water, and the intake end is square-edged and non-projecting. The difference between the water levels in the two reservoirs is 40m. a) What is the discharge if the pipe diameter is 20 cm and f = 0.007? The density of water may be taken as 1000 kg/m³. b) When this same pipe is old, assume that corrosion reduces the diameter to 18 cm and that f becomes 0.012. What will the rate of discharge be then?

You are evaluating a pipe network transporting water from a large river reservoir to the citywater storage facility. According to the pipe specifications, the pressure leaving the pipe network(continuing to city storage) cannot exceed 3 psi. Given Qa, pipe diameters (Da – Dd), determinethe pressure exiting the pipe network. Do the city designers need to reconfigure the set-up. Usethe Hazen-Williams equation to determine the head losses. All pipe lengths are 200 feet long,and the pipes are made of recently installed galvanized iron. given below Flow rate and Diameter for all 4 pipes: Q_a=42 csf, D_a=4ft, D_b=3.2ft, D_c=7ft, D_d=2.1ft.
A two floor building has two faucets, one in the basement and one in the first floor. The maximum water (\rho = 1000 kg/m3) velocity at the basement faucet, when the first floor faucet is closed, is 12m/s. The faucet diameter is 1.5 cm. Neglect all losses. (a) How much is the maximum velocity at the first floor faucet, when the basement faucet is closed? (b) What would be a maximum height (from the basement floor) for a faucet, to still get a maximum exit velocity of 5 m/s?

Water ( density 1000kg/m3) flows downward naturally through a vertical pipeline of diameter D=25 cm and length L= 100 m . Determine the pressure gradient causing flow ( USE π = 3 ; g = 10 m2/s ) ANSWER: 10 kPa/m (Although I wrote this is the answer under the question in some of the questions I posted before. Different answers were found from the answer. The exact answer to this question is 10kPa / m.)

This problem is useful for the preliminary design of a hydroturbine. From the material learned in this chapter, it is fairly simple to estimate how much power a hydroturbine can generate, given only the flow rate of water and the elevation difference upstream and downstream of the dam. A dam has a gross head of 15.5 m and a flow rate of 0.22 m3 /s. Approximating the overall efficiency of the turbine/generator to be 75%, estimate the electrical power (in kW) that couldbe produced.

The present pumping rate of crude oil through the AlaskaPipeline, with an ID of 48 in, is 550,000 barrels per day(1 barrel = 42 U.S. gallons). (a) Is this a turbulent flow?(b) What would be the maximum rate if the flow wereconstrained to be laminar? Assume that Alaskan oil fitsFig. A.1 at 60°C.
Water flows through a pipe 25 mm in diameter at avelocity of 6 m s−1.
