In the branched pipe system below, water is flowing at 0.0142 m3/sin a new, clean DN 100 Schedule 40 pipe (ID = 0.1023 m) at A. The flow splits into two new, clean DN 50 Schedule 40 pipes (ID = 0.0525 m; A = 0.00216 m2) as shown and then rejoins at B. Call the 30 m branch“a” and the other branch “b.” The friction factor in Branch ais 0.021, and the friction factor in Branch bis 0.0215.(Note that if friction factors weren’t given, you’d need to make initial guesses and iterate!)Calculate the flow rate in each of the branches. Include the effect of all minor losses in Branch bbut ignore the tee junctions. The total length of the pipe inBranch bis 60 m. The elbows are standard.(Remember to check that your final answers follow continuity!)
Two circular conduits (n=0.025) each 1.5m in diameter, serve to carry the water of a creek through a railroad embankment. When carrying flood discharges both ends of the conduits are submerged. Assuming the same slope of the pressure , what width would be necessary in two equal rectangular sections (n=0.015) and each depth is 1.2m, if they are replace the circular conduits and perform the same service?

The bed of a corrugated channel, with Manning’s coeffcient n =0.019 s/m^1/3 drops 25 m every 1500 m. The channel has a semi-circular cross section with total width of W = 10 m (i.e. radius of the semi-circle is 5 m). 1. Given that the stream has a water depth of h = 2.5 m, find the flow rate in the stream 2. A concrete divider with the same Manning’s coeffcient was installed at the middle of the stream. Given that the total flow rate in the stream stays the same, would the water depth in the stream change as a result of the divider? If so, would it increase or decrease? Would the stream velocity change? If so, would it increase or decrease? You may assume the thickness of the divider to be negligible.
