Normal depth in open channel flow is
in defining a Froude number applicable to channel flow, the length parameter used is
where A is area and Tis top width.
Froude number is a significant parameter in the study of
Match List-1 (Flow) with List-II (Value of Froude number) the following:
Subcritical flow always occurs when the depth is
The specific energy in a channel is defined as
Specific energy of a flowing liquid is defined as energy per unit weight of the liquid with respect to the bottom of the channel.
At critical detph of flow
The critical depth hc is given by .
where q the flow rate per unit width of channel
for critical depth,
A 4 m wide rectangular channel conveys 16 m3/s of water at a depth of 2.5 m. The specific energy would be about
The discharge of water through a rectangular channel of width 8 m, is 15 m3/s when depth of flow of water is 1.2 m. What is value of minimum specific energy?
