Highway Drainage

Highway drainage is the process of extracting and regulating the excess surface water on the pavement by giving the desired slope. The construction of a highway drain helps to divert the water present on the surface, and sub-grade by the means of slope. Highway drainage systems are a necessary part of smooth functioning of traffic, since the highway drainage systems provide proper disposal of unwanted substances from the highways.

SITUATION 4: Water is drained from a large reservoir using two horizontal pipes connected in series. The first pipe is 20 m long and has a 10-cm diameter, while the second pipe is 35 m long and has a 4- cm diameter. The water level in the reservoir is 18 m above the center line of the pipe. The pipe entrance is a sharp edged, and the contraction between the two pipes is sudden. Neglecting the effect of the kinetic energy correction factor, determine the discharge rate of water from the reservoir. Assume the friction factor for all pipes is equal to 0.02 and the loss coefficient is 0.05 for a sharp edged entrance, and is 0.46 for sudden contraction. 18 m Oil tank 20 m 35 m
