Water flows through a $28$ cm $($length$)$ rotameter $($Type A$)$ with an

internal diameter of $25$ mm at the top and $20$ mm at the bottom. The

float has a diameter of $20$ mm$,$ a volume of $6\mathrm{.}1$ cm$3$ and a specific

gravity of $5\mathrm{.}3$

Flowrate : $380$ L$/$hr

What is the final value of the linear flowrate through the annulus?

$($m$/$s$)$

What is the final Reynolds number through the annulus?

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