Question 1 (5 points)
Assuming the conduit in the figure is a 36"-diameter asphalted cast iron pipe flowing full,
and the outlet is at point B:
a) Calculate the head loss in the flow by the time it reaches the outlet (point B).
b) Calculate the velocity and flow in the pipe at the outlet (point B), considering
friction.
c) Sketch the EGL and HGL, and calculate their heights at the outlet (point B).
Question 2 (5 points)
Assuming the conduit in the figure is a rough asphalt lined open channel with bottom
width of 8.5' and side slopes of 4.5' horizontal to 3' vertical, and that the flow carried
must be the same as in Question 1:
a) Determine the critical depth of the flow.
b) Using the Froude number, determine the whether the flow in the channel is
supercritical or subcritical if the depth of flow is 3'.
c) Determine the normal depth of flow based on Manning's equation.
d) Determine the "critical slope" at which this channel will contain the critical depth
for a flow of 250 cfs.
e) If a gate in the reservoir at the entrance to the channel is lifted to a height of 1.20'
feet above the bottom of the channel, determine the discharge through the gate.
(Assume a gate coeff. of 0.74.)/nQuestion 3 (3 points)
The two-stage weir below is at the right edge of the reservoir. If the water elevation is
as shown in the scenario, and the breadth of the crests is 2.5 feet, determine the flow
over the weir.
