A single-phase pipeline with an internal diameter of 0.250 m handles 3200 m3 of oil per day. The density and dynamic viscosity of the oil are 850 kg m−3 and 8.30×10−3 Pa s respectively. The pipeline is 10.0 km long with a pump at the upstream end. The pipeline discharges into a vessel which operates at 1.00 bara and is at an elevation 200 m above the centre-line of the pump. The pipeline wall roughness, ϵ/D, is 0.005 and it may be assumed that minor losses are negligible. i. Calculate the mean velocity and Reynolds number of the flow. ii. Is the flow fully turbulent? Why? iii. Calculate the frictional head loss in the pipeline. iv. Determine the minimum pump discharge pressure required to meet the operating pressure of the downstream vessel.
