2.
The thickness of a sharp crested weir is kept less than
one-third of the height of water on the sill
one-half of the height of water on the sill
one-fourth of the height of water on the sill
two-third of the height of water on the sill
none of these.

3.
The property of steam function ψ is :
ψ is constant everwhere on any stream line
the flow around any path in the fluid is zero for continuous flow
the rate of change of ψ with distance in an arbitrary direction, is proportional to the component of velocity normal to that direction
the velocity vector may be found by differentiating the stream function
all the above.

2.7 m of water
7.4 m of water
5.5 m of water
