Problem $2$:

a$)$ Use Swamee and Jain formula to find the friction loss in a pipe with the following:

$e=0\mathrm{.}1mm,D=200mm,v=1{10}^{-6}\frac{m^2}{s},Q=0\mathrm{.}025\frac{m^3}{s},L=400m$

Check Re and e$/$D limitation$.$

b$)$ Use Swamee and Jain formula to find the discharge in a pipeline system with the following:

$h_f=12m,e=0\mathrm{.}2mm,D=100mm,v=1{10}^{-6}\frac{m^2}{s},L=400m$

Check Re and e$/$D limitation$.$

c$)$ Use Swamee and Jain formula to find the diameter that can deliver a $0\mathrm{.}03\frac{m^3}{s}$ in a pipe with

$L=400m,e=0\mathrm{.}2mm,h_f=26m$ if $v=1{10}^{-6}\frac{m^2}{s}$
