- 5.10 The water is supplied at the rate of 3 m3 per minute from a height of 4 m to a hydraulic ram, which raises 0.3 m3/minute to a height of 30 m from the ram. The length and diameter of the delivery pipe is 100 m and 70 mm respectively. Determine the D' Aubuisson's efficiency of the hydraulic ram if the co-efficiency of friction f = .009.Water flows from a large reservoir at the rate of 0.0137 m3/s through the system shown in the Fig. below. Calculate the pressure at B. NB: Use f = 0.017 (friction factor) and fT = 0.010 in zone of complete turbulence. Hint: Include minor losses, assume K = 1.0 for the inlet or entrance and use the applicable appendix at the back of the textbook to obtain the pipe parameters.Q3/ The water levels in the two reservoirs A and B are 104.5 m and 100 m respectively above the datum. Pipe joins each to a common point D, where pressure is 98:1 kN/m”*2 gauge at above the joint point D and height is 83-5 m above datum. Another pipe connects D to another tank C. What will be the height of water level in C assuming the same value of ‘f’ for all pipes. Take friction co-efficient f = 0-0075. The diameters of the pipes AD, BD and CD are 300 mm, 450 mm, 600 mm respectively and their lengths are 240 m, 270 m, 300 m respectively. 100 m Your answer

A 40-mm-diameter circular pipe carries water at 20°C. Calculate the largest flow rate for which laminar flow can be expected (in m3 sec-1).Problem 4: Water at 80 degree flows in a conduit with a cross section shaped in the form of an equilateral tringle. The cross-sectional area of the duct is 160 in2 and Ks= 0.0018 in. If the friction head loss is 3 ft in 150 ft. Find the approximate flow rate. Solution: 10.14 cfsA 600mm pipeline, 1550m long is to take water from a reservoir at elevation 150m and discharge it through a 150mm nozzleat elevation 25m. The pipeline is to be constructed so that at a point X, 200m from the nozzle, the pipe shall be 3m below the hydraulic gradeline. What would be the elevation of the pipe at X and what horsepowerwill be available in the jet from the nozzle? Assume f = 0.023 and no loss at entrance to pipe. Use device coefficient = 0.95.
