A pipeline connected to a reservoir discharges water 30 m below the free surface in the tank. The pipeline crosses a ridge whose summit is 9 m above the level of free surface and 300 mm distant from the reservoir. The pipe is 0.6 m in diameter and 3 000 m long and the connection is sharp and sudden. Take ƒ = 0.0075. Finda, the minimum depth below the ridge at which the pipe must be laid, if the absolute pressure in the pipe is not to fall below 3 m of water.b, the discharge
Water at four-degree Celsius flows through a pipe that has a conical shape and is sloping downward; has a height difference of 20 meters. The cross section at the bottom is one-half that at the top. If the speed and pressure of water at the top are I m/s and Pa, what is the nressure at the bottom (20 meters below the torn?

an orifice is placed at the sude od=f a 2m diameter vertical tank. the center of the orifice is 10m above the ground and 3m below the water surface. how far from the side of the tank the water reaches the ground?
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.
If the water surface elevation in reservoir B is 110 m, what must be the water surface elevation in reservoir A if a flow of 0.03 m3s is to occur in the cast-iron pipe? Use f = 0.021 for all pipes. Draw the HGL and the EGL, including changes in slope due to head loss. Neglect minor losses.
