It is desired to deliver 30,000 gal/min of water in a brickworkchannel laid on a slope of 1:100. Which wouldrequire fewer bricks, in uniform flow: (a) a V channel withθ = 45°, as in Fig., or (b) an efficient rectangularchannel with b =2y?

3. Circular clarifiers are used to remove solid materials from water. They allow continuous treatment of water and can handle fairly large flows. Solids settle to the bottom of the clarifier and are carried away by a small stream of water (the waste stream). Most of the water exits the tank as treated effluent. Assume a clarifier receives a flow of 0.10 m3/s with a solid concentration of 800 mg/L. If the waste stream consists of 3% of the incoming flow and carries 90% of the incoming solids,   a) what is the solids concentration in the waste stream, and b) what is the solids concentration in the treated effluent?

3. Three concrete pipes are connected in series as shown, if the rate of flow in the pipe is 3.53 cfs. Determine the total headloss in the pipes Pipe 1 2 3 n Diameter (in) 8 6 10 0.012 0.011 0.013 hfr = 420.1042 cfs Length in (ft) 1250 985 1970 1 2

[CE hydraulics] Does the Manning coefficient depend on the Reynolds number of the flow or on the hydraulic radius of the conduit?

Design an intake tower with gates meet the following requirement: • Nomal water surface elevation = 90 m mean sea level • Max. reservoir elevation = 96 m msl • Min. reservoir elevation = 80 m msl • Bottom elevation = 71 m msl • Flow rate = 57369.6 m³/day., Velocity = 0.083 m/s • = 0.6 , Density for water =1000 kg/m³ , Density for concrete =2310 kg/m Estimate water elevation that make safety factor =1 4.5m Uppr gate 2m 2m Gate Lower gate 1m 6m 2 m 4 m 2 m 2m

Problem 9-36 pipe bend shown is in a horizontal plane. A fluid weighing 8.615 kN/m enters the bend with a velocity of 3.5 m/s and a pressure of 280 kPa. Neglecting head loss, find the force required to hold the bend in place. The Ans 10.4 kN 65 200 mm O 80 mm diam

A Vertical sluice gate 4m wide and 2m deep is hinged at the top. A liquid of specifie grality 1.5 Stands on the upstream of the gate up to 3.5m above the top edge f the gate and water on the stream sile up to the top Of the gate. find he resultant force acting on the gate 1). The paint at which the resultant force acts .
