6.29. The flowrate passing over this sharp-crested weir in a channel of 1 ft width is 3.5 cfs. Calculate the magnitude and direction of the force exerted by the water on the weir plate.

Solution

1.the sharp-crested height h=3

width b=1 and length=3.5

maginitude= B-L/2>2H

=4-2/2>2.2

=2/1>4

2.4

=0.5

MAGINITUDE=0.5
