39. (a) Water flows under gravity from Reservoir A to Reservoir B first through a 900-m long pipe (pipe a) and then through two pipes (b and c) in parallel. The lengths, diameters and friction factors of the pipes are listed in the table. The water level in Reservoir A is always higher than that in Reservoir B by 20 m. Calculate the total discharge between the reservoirs. Neglect all minor losses. (15 marks) (b) Which of pipes b and...
For the shown system, the pump head discharge curve is Hp = 20-30 Q where the head in m and the discharge in m/s, HA = 10 m, He = 25 m, Hc = 15 m. The diameters for all pipes are 400 mm, the length for pipes 2 and 3 are 1500 m length. Assume fully turbulent flow in all pipes and surface roughness 0.15 mm. Find the water flow distribution when: a) The pipe 1 is not used...
5) A 6-km cast-iron (new) pipeline conveys 0.32 m/s of water at 30°C. If the pipe diameter is 30 cm, compare the head loss calculated (a) Darcy-Weibach equation (f = 0.0195), (b) the Hazen- William equation (Chw = 130), and (c) the Manning equation (n=0.011). Use Excel. (Max. 15 Points) 6) Pipes AB and CF in figure below have a diameter of 48 in possess a Hazen-Williams coefficient factor of 100 and carry a discharge of 120 ft/s. The length...
7.14 The pump in Fig. 7.20 delivers water from the lower to the upper reservoir at the rate of 0.057 m3/s. The energy loss between the suction pipe inlet and the pump is 1.83 m and that between the pump outlet and the upper reservoir is 3.66 m. Both pipes are 6-in Schedule 40 steel pipe. Calculate (a) the pressure at the pump inlet, (b) the pressure at the pump outlet, (c) the total head on the pump, and (d)...

Q4. A pump draws water from a large reservoir and delivers it to another reservoir whose water surface is 10 m higher than the pump centreline and that the pump is 1.5 meter above the suction reservoir. The total suction and deliver pipe used is 21.1 m in length, 9 cm in diameter and has a Darcy friction factor f0.0339. The pump operates at 750 rpm and its characteristic performances are given in table below: Q (m3 s H (m)15...

2. Pipes 1, 2, 3, and 4 have lengths of 300 m,240 m, 210 m, and 450 m, all being new cast-iron. Pipe 2 and 3 are laid in parallel, both drawing from 1 and discharging into 4. If 1, 2, and 4 have diameters of 200 mm, 150 mm, and 250 mm, respectively. Determine the diameter of 3 when the discharge through the system is 45 liters/sec. under a total headloss of 8 m. Assume f 0..02...
