$4$ Points

For a heat exchanger with the cross$-$section shown below.

a$.$ Compute the Reynolds number for the flow of water at $100$ C at a volume flow rate of $225\frac{L}{m}in$ inside the heat exchanger.

b$.$ If the heat exchanger is $1\mathrm{.}8$ m long, compute the head loss $($hL$)$ in the system. The material is a commercial steel.

Note $1$: $1\frac{m^3}{s}=60000\frac{L}{m}$inI'm
