A rightangled triangular channel symmetrical in section about the vertical carries a discharge of 5 m^{3}/s with a velocity of 1.25 m/s. What is the approximate value of the Froude number of the flow?
A rectangular channel is 5 m wide and 3 m deep. Water is flowing in the channel for a depth of 2.5 m. The hydraulic radius is

Flow depths across a sluice gate are 2.0 m and 0.5 m. What is the discharge (per metre width)?
Given that
S_{0} = slope of the channel bottom
S_{e} = slope of the energy line
F = Froude number
the equation of gradually varied flow is expressed as
A rectangular channel is 6 m wide and discharges 30 m^{3}s^{1}. The upstream depth is 2.0 m, acceleration due to gravity is 10 ms^{2}. Then, what is the specific energy (approximate)?
For a smooth hump in a subcritical flow to function as a broad crested weir, the height ΔZ of the hump above the bed must satisfy which one of the following?
(E_{1} = Specific head upstream of the hump, E_{c} = Specific head at the critical" depth y_{c}) (Neglect friction effects)
A hydraulic jump occurs at the top of a spillway. The depth before jump is 0.2 m. The sequent depth is 3.2 m. What is the energy dissipated in m (approximate)?
What is the normal depth in a wide rectangular channel carrying 0.5 m^{2}/s discharge at a bed slope of 0.0004 and Manning’s n = 0.01?
