(b) A regulator was constructed to pass a Leliavsky discharge in a canal of depth equals to 2.2 m at u/s side and an allowable drop in water surface (Dw) equals to 0.1m. By considering velocity head (do not neglect it): 1. Derive a formula that can be used to calculate hy or AH directly in terms of yt Cd and Dw, equation, starting with Leliavsky q= Cd y√√2gAH. 2. What would be the discharge passing through the regulator? Hint: Cd-0.92; H-h+ hv; yt-h-Dw US WL ΔΗ Dw E.L. - AH=h+h, yt = Dw + hv yt D/S W.L.

z=174 m A B z=152 m z=91 m T = and Op ≈pg əx (Pump) C F A pump is used to deliver water from a reservoir to a large tank for a flowrate of 1310 L/s at 20 °C. The connecting pipe connects the reservoir at B with a square-edged entrance. From B to C, the pipe is 760 m long and has three gate valves, four 45⁰ elbows, and two 90° elbows. Gage pressure at C is 197 kPa. From F to G, the pipe is 760 m long and contains two gate valves (Kg.-0.136), four 90° elbows (K90-0.51) and connects the tank with an exit (Kext=1). All pipe is 508 mm in diameter (D) and made by cast iron ( = 0.26 mm). 1) Calculate the average velocity of water in the pipe. 2) Calculate the gage pressure at F. z=104 m 3) If the pump's efficiency is 80%, calculate the power input to the pump. 4) If the shear stress can be calculated using the equation D Op hL major 4 0x L Calculate the average wall shear stress in section F-G.
