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).
