Water flows through a $28$ cm $($length$)$ rotameter $($Type A$)$ with aninternal diameter of $25$ mm at the top and $20$ mm at the bottom. Thefloat has a diameter of $20$ mm$,$ a volume of $6\mathrm{.}1$ cm$3$ and a specificgravity of $5\mathrm{.}3.$ Flow rate of $380$ L$/$hr$.$

$1.$ What is the final value of the linear flowrate through the annulus?$($m$/$s$)$

$2.$ What is the final Reynolds number through the annulus?

$3.$ How far from the bottom is the float under these conditions? $($cm$)$

Iterate until a constant is obtained. $4$ iterations should be enough
