EAH 225 HYDRAULICS - Open Channel HydraulicsTutorial : Application of the Energy Equation and Hydraulic JumpThe discharge of water over a spillway 12 m wide is 283 m/s into a stilling basinof the same width. The Bukit Merah lake level behind the spillway has anelevation of 60 m, and the Kurau River water surface elevation downstream of thestilling basin is 30 m. Assuming a 10 percent energy loss in the flow down thespillway, find the invert elevation of the floor of the stilling basin so that thehydraulic jumps forms in the basin.Bukit Merah LakeRiver Kurau60 mStilling Basin30 mDATUMSpillway

a) A pump delivers water at a temperature of 20 °C from one reservoir to another high reservoir. The water level difference between the two reservoirs is 6 m. A galvanized iron piping system consists of a 20 m delivery pipe, 10 cm diameter, a reentrance entrance, two long sweep elbows 90°, and an exit. Sketch the diagram with the relevant hydraulic and energy grade line. b) With the help of a Moody chart given in the Appendix, determine the pump efficiency required by the pump's in Q3(a) if the pumping power and flow rate are 2 kW and 40 m³/h, respectively.
2.Water flows through a rectangular channel with a width b = 2 m and a height (Pw) = 1 m, the flow rate ranges from Qmin = 0.02 m^3/s and Qmax = 0.60 m^3/s.
