The duct shown below carries d m/s of water at 90 C in the shaded area. The duct is e metres long. The thickness of all the solid walls is 2.77 mm. All the solid walls are commercial steel. Calculate the Reynolds Number and the friction head, hl. The details are given below. a (mm) = b (mm) = c(mm) = d (m/s) = e (m) = 150 300 450 0.75 95 Both mm square outside Water Density (kg/m) Water Viscosity (Pa.s) Flow Area (m) Wetted Perimeter (m) Hydraulic Radius (m) Water Velocity (m/s) Reynolds Number E(m) D/& Factor Friction Factor, f Friction Head, h (m)
