ANS: $V_1=5\mathrm{.}32\frac{(m)}{(s)},V_3=5\mathrm{.}83\frac{(m)}{(s)},V_4=5\mathrm{.}24\frac{(m)}{(s)}$

Problem $2$: A galvanized iron pipe with a roughness height of $0\mathrm{.}15$ mm with a diameter of $0\mathrm{.}05$ m and a length of $110$ m has experienced head loss due to friction of $15$ m $.$ The fluid is water with kinematic viscosity of $1{10}^{-6}\frac{m^2}{s}.$ Use Moody chart to find the friction factor. Calculate the flow rate.

ANS: $Q=0\mathrm{.}0044\frac{m^3}{s}$
