Water flows through a pipe under gravity flow. The pipe drops 4 m in elevation for every 140 m of horizontal pipe. Determine the diameter of pipe (in cm) that would be required to carry 190 L/s of water using the Manning Equation. Assume n = 0.013.

When a 22 cm pipe flows full of water under gravity flow the flow rate is 0.050 m3/s. If the pipe flows partially full, determine the depth of flow that would result (in cm) in the pipe when the ratio of the partial flow to the full flow (q/Q) is 0.80. Round answer to one decimal place.
4. An old, rough-surfaced, 2-m-diameter concrete pipe with a Manning coefficient of 0.025 carries water at a rate of 5.0 m'/s when it is half ful. This pipe is to be replaced by a new smooth pipe with a Manning coefficient of 0.012. Determine the diameter of the new pipe if it also is to flow half full with a flow rate of 5.0 m'/s Water initially flowing in the horizontal section of pipe of diameter 12.00 cm shown in...
(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...
(b) Water flows under gravity through a pipeline connecting two reservoirs as shown in Figure 2. The pipeline consists of 2 km of pipe diameter 400 mm and sand roughness equivalent 0.03 mm followed by an abrupt change to 3 km of 500 mm diameter pipe of sand roughness equivalent 0.08 mm. The pipe discharges as a free jet into a reservoir. The difference in elevation between the water surface of the upstream reservoir and the discharging jet is 21...

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...
Water flows at a rate of 22 L/min through a horizontal 7.0-cm-diameter pipe under a pressure of 17.0 Pa . At one point, calcium deposits reduce the cross-sectional area of the pipe to 21 cm2 . What is the pressure at this point? (Consider the water to be an ideal fluid.) Express your answer using two significant figures.
Water with pressure of 190 kPa flows down hill through a pipe with a 3.90 cm diameter hose at a speed of 1.2 m/s. It then exits through a smaller pipe m of diameter 1.50 cm which is 5.00 m below the upper pipe. a. What is the speed of the water exiting at the lower pipe opening? b. What is the water pressure at the exit of the lower pipe. ?
