Water flows from a large 4m detention basin (100m by 50m) along a 200mm diameter pipe for a distance of 100m at a slope of 1:200. The pipe centerline is 300mm above the base of the basin and it drains freely to a nearby channel. Calculate the steady flow rate if (a) the flow is assumed ideal, (b) the pipe is considered smooth for the purposes of the Moody Diagram (c) the pipe has a relative roughness of 0.006 (d)...

ater to be pumped from a lake to a storage tank in a ranch. Water temperature is 60 F.The clevation of the pipe exit that will feed the tank is 50 ft higher than the lake water surface. It is required that a 4-hour pumping time will feed the storage tank by 1,200 gallons of water. While operating at the required flow rate, the pump will generate a head of 60 n. Coeflicients of minor loss due to filtering, fittings,...

During a big fire in the Unita Mountains, firefighters decide to use a large lake as a source of water (20°C, density of 998.2 kg/m^3). The firefighters place a 3-inch diameter hose at the bottom of a 10-foot deep lake and pump water to a cabin that is on fire (the entire hose is 3 inches in diameter). The outlet of the hose is 30 feet higher than the lake surface. The work performed by the pump is 200 J...

Water (density 998 kg/m', absolute viscosity 1.12x10 Ns/m2) is pumped from a lake into a reservoir at a rate of 0.7 m/s. The water flows through a re-entrant opening, a valve, and a sharp-edge...
Water (density 998 kg/m', absolute viscosity 1.12x10 Ns/m2) is pumped from a lake into a reservoir at a rate of 0.7 m/s. The water flows through a re-entrant opening, a valve, and a sharp-edged exit, which have loss coefficients of 0.8, 10, and 1, respectively. The pipe has an absolute roughness of 1x104m and di of 0.30 m. The pump efficiency is 65%. A) Is the flow in the pipe laminar or turbulent? (2 points) B) What is the power...

4. (20 pts) A rapid mixing basin is designed to process 3.0 MGD of water. The basins will be square, and the depth is assumed to be 1.times of the width. Use a detention time of 30 s and velocity gradient of 750 s'. Two basins will be constructed each having a capacity to process exactly half the entire water flow. Determine: (a) Dimensions of the basin (L, W and H) (b) Power input (hp) (c) Rotational speed (rpm) of...

Water is pumped from a well to a water tower (an above-ground reservoir) through a 330 ft long galvanized iron pipe (ε-0.0005 ft) with a 2-in diameter. The water surface in the well is 10 ft below the ground and the water surface in the tower is 60 ft above the ground. The water is to be delivered at a rate of at least 370 L/min. The sum of the minor loss coefficients is 2.1 a) Using the pump performance...
