A heat exchanger $($shell and tube$)$ is used to increase the temperature of the water.

Tube length: $300$ mm

Inside diameter of tube: $11$ mm

Shell diameter: $100$ mm

Constant Water flow rate $($kg$/$s$)=0\mathrm{.}119$

Temperature of water, inlet $=20$

Temperature of oil, inlet $=40$

Oil flow rate $($ml$/$s$)=0,20,60,100,140,180$

Water $($Oulet temperature, $\backslash$deg C$)=$ w$1$ w$2$ w$3$ w$4$ w$5$ w$6$

Oil $($Outlet temperature, $\backslash$deg C$)=$o$1$ o$2$ o$3$ o$4$ o$5$ o$6$

Material Balance $($Water$)$

$$Flow rate $($ml$/$s$)=40$

$$t$($s$)=20$

$$m $($kg$)=1\mathrm{.}3$

$1.$Perform energy balance calculations of the water, oil and any energy losses$/$gains through the pipes

$2.$ Using the rotameter values $($flow rates$)$ and the measured amount of discharge water,determine the mass balance across the heat exchanger for various flow rates of oil and water.
