A pipeline carries a multiphase flow of oil and gas. The fluid properties of the oil are density ρO = 800 kg/m³ and viscosity μO = 0.086 Pa·s. The fluid properties of the gas are density ρG = 0.100 kg/m³ and viscosity μG = 0.00002 Pa·s. The volumetric fraction of oil in the flow is 0.8. At a particular point in the pipeline, the flow regime transitions from stratified flow to annular flow. Determine the Reynolds number at the transition point for both the oil and gas phases.
