QUESTION $5$

A$.$ Shows that;

$q=\sqrt[\phantom{2}]{g}{H}^{\frac{3}{2}}(\frac{P}{H})$

When flow rate, $q(\frac{m^3}{s}\frac{?}{m})$ over the spillway assume would affected by height of water over weir,

$H(m),$ height of weir, $P(m)$ and gravity, $g(\frac{m}{s^2})$

B$.$ A model boat $\frac{1}{100}$ size of its prototype has $0\mathrm{.}12N$ of resistance when simuating a speed of $5\frac{m}{s}$

of the prootype. By using Froude number calculate the corresponding resistance in the prototype.

Water is the fluid in both cases and frictional forces can be neglected.
