The depth of water at a location a few meters upstream from a frictionless, broad-crested weir is 1.90 m. The channel in which the weir is installed is rectangular and 3.00 m wide. a) If the weir is 1.30 m high and has a crest length of 3.00 m (i.e. spans the full width of the channel), determine the discharge in the channel. b) Determine the velocity of the water near the crest of the weir where critical flow occurs. c) Determine the velocity of the approach and comment on whether it is acceptable, in this case, to neglect the approaching velocity head when assessing the specific energy.

The depth of water at a location a few meters upstream from a frictionless, broad-crested weir is 1.90 m. The channel in which the weir is installed is rectangular and 3.00 m wide.
a) If the weir is 1.30 m high and has a crest length of 3.00 m (i.e. spans the full width of the channel), determine the discharge in the channel.
b) Determine the velocity of the water near the crest of the weir where critical flow occurs.
c) Determine the velocity of the approach and comment on whether it is acceptable, in this case, to neglect the approaching velocity head when assessing the specific energy.
