On a farm, water $(\backslash$gamma $=9810$ N$/$m$3$ & $\backslash$mu $=1\mathrm{.}15$e$-3$ Pa$*$s$)$ is delivered from a pressurized storage

tank to a watering tank. Calculate the required air pressure above the water in the tank to

produce $($a$)$ laminar flow $($Re $=2000)$ and $($b$)$ turbulent flow $($Re $=5000).$ Note that L $=123$

m$,$ h $=1$ m$,$ and D $=2$ in$.$ The pipe is steel $(\backslash$epsi $=4\mathrm{.}6$e$-5$ m
