A river with a nearly rectangular cross section goes through a lateral channel
contraction due to the presence of a bridge, and the water surface elevation y
decreases by 1m at the contraction. Assuming there is no energy loss through the
contraction and the flow is not choked, how much would the velocity head change at
the contraction? Is the flow subcritical or supercritical before the contraction? (hint:
check the energy profile)
The discharge of water through a rectangular channel of width 6.0 m, is 18 m3/sec when depth of flow of water is 2.0 m. draw Specific Energy Graphs and find :
a) Critical depth
b) Specific Energy
c)Minimum Energy
d) Critical velocity
