As you all know, Dr$.$ Rahman has a chicken farm full of smart chickens. Being smart they are very

bored because all they do is lay eggs. The smart chicken decided to build a water slide for

amusement. The slide's centerpiece is a massive hydraulic jump intended to swamp, flip, and

launch riders called "Pawk Pawk" $($in chicken language it means "Get me out of here, its

ridiculous"$).$ The slide happens through a rectangular channel $(n=0\mathrm{.}015)10m$ wide that carries

a discharge of $50cms.$ Drawing of water slide is shown on Figure $1$ next page. The energy losses

between sections $C$ and $1$ can be neglected. Critical depth occurs at section $C$ just before the slide.

The Institute for Smart Chicken Extreme Entertainment $($ISCEE$)$ has published a Thrill Scale for

hydraulic jumps based upon the ratio of the change in depth across the jump to the jump's length,

$\frac{y_2-y_1}{L}.$ This scale is given below.

$($a$)$ What will be the Thrill Score for the hydraulic jump?

$($b$)$ Name one design change that could increase the Thrill Score and provide justification for this

answer.

Hint: Use Figure given to find out the length of the jump $($L$).$

Please use steps in detail.
