Since this pipeline was calculated with a flow rate of 400 gpm, this example will calculate the head loss for 200 gpm and 800 … WebReynolds number depends on flow velocity, passage diameter, and water kinematic viscosity. Reynolds numbers of 2000 to 4000 are transitional, meaning flow may be laminar or turbulent. A Reynolds number above 4000 generally results in turbulent flow. Water viscosity decreases with increasing temperature, thus yielding a higher Reynolds number.

WebBecause R is less than 2000, this flow is laminar. If the flow rate is tripled to 150,000 bbl/day, the Reynolds number becomes 3570 and the flow will be in the critical region.At flow rates above 168,040 bbl/day, the Reynolds number exceeds 4000 and the flow will be in the turbulent region.Thus, for this 16-in pipeline and given liquid viscosity of 250 cSt, … WebTo use this online calculator for Reynolds Number, enter Density of Liquid (ρl), Fluid Velocity (uFluid), Pipe Diameter (dpipe) & Dynamic Viscosity (μviscosity) and hit the calculate button.
