Water discharges from a pond through a rectangular opening that is 1.2m wide and 0.5 m high. Use Cd=0.62.

a) Find the discharge through the opening if the water surface in the pond is 0.3m above the opening invert (bottom of the pipe).

b) Find the discharge through the opening if the water surface in the pond is 1m above the opening invert.

A fountain in a pond draws water from the base of the pond, passes it through a pump with ?? = 25 ?, and along a pipe of length L=3 m, diameter D=15 cm and friction factor f=0.03. The pipe has three 90deg bends (?? = 0.8) before passing through a contraction nozzle (?? = 0.5 based on the upstream velocity) such that the diameter of the outlet nozzle is d=5 cm. The flow then leaves the nozzle moving in...

Water approaches a sharp-crested rectangular weir through a channel that is 2 m wide. The depth of flow in the channel is 1 m. The weir crest is 0.6 m above the base of the channel and has a crest width of 0.8 m. It is located in the centre of the channel. Assuming a coefficient of discharge of 0.61, and ignoring side contractions, determine the discharge over the weir: a) Assuming the approach velocity is zero b) Including the...

EXAMPLE 6.1 A trapezoidal irrigation canal has a bottom width of b¼1.2m, side slopes of m¼2 (2H:1V), and a longitudinal bottom slope of S0¼0.0005. A rectangular sharp-crested weir placed in this channel has a crest height of p¼0.70m, and a crest length of Lw¼0.80m. The water surface elevation at the approach section is h0¼0.77m above the weir crest. Determine the discharge in the canal.

Water flows through a pipe that gradually descends from a height of 6.78 m to the ground. Near the top, the cross-sectional area is 0.4 m2, and the pipe gradually widens so that its area near the ground is 0.8 m2. Water leaves the pipe at a speed of 16.8 m/s. What is the difference in the water pressure between the top and bottom of the pipe?
