In a wide rectangular channel having a depth y = 1.8 m and unit width discharge q = 1.5 m²/s, an on-going construction project over the channel requires that a number of cylinder platforms (only two are shown in the plan view below) spaced at distance bị = 6 m be placed in the channel. Assume no energy losses between locations 1 and 2, determine the maximum diameter of the cylinders without creating upstream backwater effect (i.e., without increasing the upstream depth). bi

Reservoirs A, B and C are connected by pipelines 1, 2 and 3 respectively which meets at the junction D. The elevation of reservoir A s 300 m, while that of C Is 277 m. Reservoir B is higher than reservoir A. The rate of flow out of reservoir B is 560 liters/sec. Compute the elevation of Reservoir B in m Pipe 1 (D=900 mm; L=1500 m; f=0.0208) Pipe 2 (D=600 mm; L=450 m; f=0.0168) Pipe 3 (D=450 mm; L=1200 m; f=0.0175) Round your answer to 3 decimal places.
Q21( Water is pumped at a rate of 150 m³/hr to the upper reservoir as shown in Fie 2. Calculate the power required to drive the pump. Take pump efficiency as 80%.
A 7350 m long, 1050 mm concrete pipeline connects an upstream reservoir (watersurface elevation 433.3 m) to a downstream reservoir (water surface elevation 423.1 m). Adischarge valve at the downstream end is used to control flow; when this valve is fully open,the measured discharge in the pipeline is 920 L/s under the naturally available head difference.(a) Assuming fully developed turbulent flow and that all other local losses are negligible,estimate the loss coefficient k for the fully open valve (assume f = 0.015).(b) Because of increasing urban development, the flow under the natural head difference isconsidered to be inadequate and it is proposed to increase this flow with pumping. The head-capacity curve for the pump can be approximated by the equation H = 8 – 3.5Q2 in which H isthe total dynamic head on the pump (in m) and Q is the discharge (in m3/s). What is thedischarge that can now be obtained from the system where the pump is installed at a cross-section of the pipeline?

Water flows in a horizontal, rectangular channel initially 10 feet wide and 2 feet deep. The initial velocity is 6 ft/s. This flow encounters downstream a simultaneous downward step and constriction. No energy losses are associated with these changes in channel configuration. a. What is the specific discharge, q: i. Upstream (for w= 10 feet)? ii. Downstream (for w = 6 feet)? b. What specific energy, E, is associated with the flow as initially specified (at the upstream location)? c. What is the minimum energy needed to pass the full discharge at the downstream location? d. What is the height (Az) of the smallest downward step necessary for the upstream flow conditions to remain as specified?
