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.
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?
