The volume flow

over a weir depends on the upstream height
, the width of the weir
, and acceleration due to gravity. Obtain a relationship between the variables in terms of dimensionless parameters.

The speed

of free surface gravity wave in deep water depends on the depth
, wave length λ, density ρ and acceleration due to gravity. Determine, using dimensional analysis, a functional relationship between the varaibles.
