Oil of SG \\( =0.87 \\) and a kinematic viscosity \\( v=2.2 \\times 10^{-4} \\mathrm{~m}^{2} / \\mathrm{s} \\) flows through the vertical pipe shown in the figure below at a rate of \\( 3 \\times \\) \\( 10^{-4} \\mathrm{~m}^{3} / \\mathrm{s} \\). Determine the manometer reading, \\( h \\). Assume \\( S G_{m}=1.3, D=18 \\mathrm{~mm}, I=4 \\mathrm{~m} \\).
