Find the discharge of water flowing over a rectangular notch of 2 m length when the constant head over the notch is 300 mm. Take C = 0.60.

What is the water flow rate (Q) of the shown pipe? Friction head loss is given by f = 0.2(L/D)v/2g. Draw the Energy and Hydraulic Grade Lines. (Density of water is 1000 kg/m3) 5m Diameter = 20 cm %3! Lenghth of pipe =1 km %3D

88 cm d 17 cm In the fountain shown, water flowing at 35 lpm exits the weir at the top, with a stream that is 17 cm wide and 0.20 cm thick. Determine the diameter of the stream (cm) at a point 88 cm below the weir, assuming that the flow has a cylindrical shape at this location Solution: 1.3 cm

If the water surface elevation in reservoir B is 110 m, what must be the water surface elevation in reservoir A if a flow of 0.03 m^3/s is to occur in the cast iron pipe. Use f= 0.0021 for all pipes. (DO NOT ROUND OFF)
