Water at $15^{\circ}C$ ($\rho=999.1$ $kg/m^3$ and $u=$$\displaystyle{1.138\cdot 10^{-3}}$ $kg/ms$) is flowing steadily in a $28$ $\displaystyle{m}$ long and $12$ $\displaystyle{cm}$ diameter horizontal pipe made of stainless steel at a rate of $6$ $litres/s$. Determine:
(a) the pressure drop
(b) the head loss
(c) the pumping power requirement to overcome this pressure loss.
Note: WebWork will use the Haaland equation for the friction factor.

1. $\displaystyle{Drop}$ = $\displaystyle{kPa}$
2. $\displaystyle{Head}$ $\displaystyle{loss}$ = $\displaystyle{m}$
3. $\displaystyle{Power}$ = $\displaystyle{kW}$
