Similar Civil Engineering (CE) Doubts

Two reservoirs are connected by two parallel pipes of equal length and of diameters 20 cm and 10 cm, as shown in the figure (not drawn to scal e). When the difference in the water levels of the reservoirs is 5 m, the ratio of discharge in the larger diameter pipe to the discharge in the smaller diameter pipe is________. (round off to two decimal places)(Consider only loss due to friction and neglect all other losses. Assume the friction factor to be the same for both the pipes) Correct answer is between '5.6,5.7'. Can you explain this answer?

Two reservoirs open to the atmosphere are connected by a pipe 800 metres long. The pipe goes over a hill whose height is 6 m above the level of water in the upper reservoir. The pipe diameter is 300 mm and friction factor f = 0.032. The difference in water levels in the two reservoirs is 12.5 m. If the absolute pressure of water anywhere in the pipe is not allowed to fall below 1.2 m of water in order to prevent vapour formation, calculate the length of pipe in the portion between the upper reservoir and the hill summit. Neglect bend losses. Correct answer is 'Range: 180 to 200'. Can you explain this answer?

Two identical pipes (i.e. having the same length, same diameter, and same roughness) are used to withdraw water from a reservoir. In the first case, they are attached in series and also discharge freely into the atmosphere. In the second case, they are attached in parallel and friction factor is same in both the cases, the ratio of the discharge in the parallel arrangement to that in the series arrangement (round off to 2 decimal places) is _____ Correct answer is '2.828'. Can you explain this answer?

Three identical pipes of length l, diameter d and friction factor f are connected in parallel between two reservoirs. What is the size of a pipe of length l and of the same friction factor f equivalent to the above pipe?

Two reservoirs are connected through a 300 mm diameter pipe line, 1000 m long as shown in figure. At a point B, 300 m from reservoir A, a valve is inserted on a short branch line which discharges to the atmosphere. The valve may be regarded as a rounded orifice 75 mm diameter, Cd = 0.65. If friction factor f for all the pipes is 0.013. Estimate the leakage through the short pipe line at B (in m3/s). Correct answer is 'Range: 0.04 to 0.06'. Can you explain this answer?
