Question

0.30m3/s of fuel oil flows in a horizontal smooth rectangular duct of height 0.6m. The ratio of width to height is 1:2. The whole cross-section remains wet when the water is flowing inside the duct. Calculate the head loss in meter (with 2 decimal places) in 20 m of this duct. (T= 20 °C; f = 0.316Re^-0.25; ρ_oil = 920 kg/m³; ν_oil = 1.25*10^-6 m²/s)
