3. (20%) Water of 15°C temperature is pumped at a rate of 0.01 m/s through the 800-m long and 10-cm diameter drawn tubing from the upstream reservoir at an elevation of 10 m to the downstream reservoir at an elevation of 30 m. The pump is located at an elevation of 10 m below the datum and at a distance of 350 m from the upstream reservoir as shown. (a) Find the values of the Reynolds number and the friction...
Problem 4 (50 points) water is discharged from a reservoir at a rate of 18.103 m2/s using two horizontal cast iron pipes nected in series and a pump between them. The first pipe is 20 m long and has a 6-cm diameter, while the second pipe is 35 m long and has a 4-cm diameter. The water level in the reservoir is 30 m above the centerline of the pipe. The pipe entrance is sharp-edged. Losses associated with the connection...
Q2. 50 marks Water at 20°C is pumped at 5.7 m3 min-1 from the lower to the upper reservoir, as in Fig. 2. The free surface of the upper reservoir is at height Z2 = 46 m, and of the lower reservoir at 21 = 15 m. The pipe diameter before and after the pump is D= 15 cm. Pipe friction losses are approximated by h = 27v2/(29), where V is the average velocity in the pipe. The gravitational acceleration...

1. Water is pumped from a low reservoir to a high reservoir that is 20 m higher in elevation. The water is flowing at 1.5 m/s through a 305 mm internal diameter piping system. The water is at 18 degrees C. There are 1,000 m of piping, six standard 45 degree bends, two standard 90 degree bends, a branch flow tee, three gate valves, a swing check valve, a square inlet and a square outlet. The piping and valves are...
8-C) As shown below water is pumped and sprayed through a nozzle into the atmosphere at 20 m/s at an elevation 10 m above the reservoir surface. The mass flow rate is 40 kg/s and the volumetric flow rate is 0.040 m3/s. The large diameter inlet pipe total length is 50 m. The pump effidency is 65%. The longer smaller diameter pipe leaving the pump is 200 m in total length. The pipes have different diameters as indicated below. The...
(b) Water flows under gravity between two reservoirs through a pipe of length 5000m. The diameter of the pipe is 0.2 m and the roughness size is 0.04 mm. The water levels in the two reservoirs are maintained with a difference of 50 m. Determine the discharge through the pipe. Neglect all minor losses. Use the attached Moody diagram for estimation of friction factor. (10 marks) (c) In (b), now include entry loss at the upper reservoir with loss coefficient...
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...
Water is to be withdrawn from a 3-m-high water reservoir by drilling a 1.5-cm- diameter hole in the center of the bottom surface. Disregarding the effect of the kinetic energy correction factor, determine the flow rate of water through the hole for a) a sharp edged entrance followed by threaded 90° bend and then a 3.5m length of wrought iron pipe and finally a fully open Globe Valve b) redo a) for the ideal case with no viscous losses
