FLUID$\_$PROJECT$\_$Version $1$

Part One: $(5$ marks$)$

The inlet pressure, the Q of water and the diameter are known. $P=700$kPa,$Q=10$lite$\frac{r}{sec}$ and $D=4cm$

Find the pressure drop

Part two $(5$ marks$)$

The pressure drop is known $20\%$ of the inlet pressure find Q

Part three $(5$ marks$)$

The pressure drop and $Q$ are known find the diameter. Pressure drop $=30\%$ of $P$ in and $Q=15$ liter $/$ sec

Here are the steps to follow

$($a$)$ If the gage pressure at the inlet of the system is $200$ kPa during a shower and the toilet reservoir is full $($no flow in that branch$),$ determine the flow rate of water through the shower head.

$($b$)$ Determine the effect of flushing of the toilet on the flow rate through the shower head. Take the loss coefficients of the shower head and the reservoir to be $12$ and $14,$ respectively.

$($c$)$ Calculate the pressure drop in the system.
