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.

Question

: Water flows over a smooth submerged object in a channel of width 1.2 m. The water
depth upstream of the object is 2.2 m and the water depth downstream is 0.5 m.
i) Use the Bernoulli and Continuity equations to calculate the discharge within the
channel, and sketch the energy grade line and hydraulic grade line for this problem.
ii) The measured discharge in the channel is 2.4 m³/s. Calculate the discharge
coefficient, and describe what this physically represents.
iii) A pitot tube (or stagnation tube) is placed in the downstream part of the channel,
where the water depth is 0.5 m. Calculate the height to which water will rise within
this pitot tube (above the depth of water in the channel).
