(b) A regulator was constructed to pass a Leliavskydischarge in a canal of depth equals to 2.2 m atu/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 tocalculate hy or AH directly in terms of ytCd and Dw,equation,starting with Leliavskyq= Cd y√√2gAH.2. What would be the discharge passing through the regulator?Hint: Cd-0.92; H-h+ hv; yt-h-DwUS WLΔΗDwE.L.-AH=h+h, yt = Dw + hvytD/S W.L.

Hi, please could someone show me how U2 = 1.98m/s. This is the correct answer but i've tried a few methods and can't quite get there! Any notes on the method alongside calculation would be great :) The two pipes are parallel, Kexit =1 for pipe 1 and pipe 2, entry losses can be ignored.

Problem 2: (a) A pump curve for a pump running at 800 rpm is given by h, =20–4713 Q² , where h, is in meters and Q in cms. What will be the pump curve for the same pump running at 1200 rpm? (b) Find the discharge and head for the pump that is running at 1100 rpm, when the same pump running at 1600 rpm produces head of 75 ft and discharge of 7000 gpm (part (b), is not related to part (a) in any way).

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).

Thank you professor !!
Trapezoidal cross section given in the figure on the side It is requested to pass a flow rate of 5 m/s through the channel. Accepting that n=0.0167 and Jo=0.0005 in this section; size the cross section to be optimal from the hydraulic direction.
1. The performance data of a water pump follow the curve fit Havailable =Ho +aV, where the pump's shutoff head Ho="K", coefficient a="Y" m/(Lpm)?, the units of pump head H are meters, and the units of Vare liters per minute (Lpm). The pump is used to pump water from one large reservoir to another large reservoir at a higher elevation. The free surfaces of both reservoirs are exposed to atmospheric pressure. The system curve simplifies to Hrequired =(Z2-Z1)+bV², where elevation difference z2-z1="X" m, and coefficient b = "L" m(Lpm)?. Calculate the operating point of the pump (a) V. operating and (b) Hoperating) in appropriate units (Lpm and meters, respectively). Read the equation carefully. (Zz-Z:) Но b a Y K L 0.0479 4.9 0.029
