The flow regime (either laminar or turbulent) is determined by evaluating the Reynolds number of the flow refer to (Flow Velocity profiles). TheReynolds number, based on studies of Osborn Reynolds, is a dimensionless number comprised of the physical characteristics of the flow. Equation 1 is use...
Reynolds number = (Fluid velocity x Internal pipe diameter) / Kinematic viscosity Laminar Flow in a Pipe Laminar flow occurs when the calculated Reynolds number is less than 2300 and in this case the resistance to flow is independent of the pipe wall roughness. Turbulent Flow in a Pipe Turbule...
Reynolds Number Equation The Reynolds Number is the ratio of the inertial and viscous forces of a fluid's flow: $$Re = \frac{inertial force}{viscous force} $$ The expressions for the two terms simplify into a ratio that provides the Reynolds number formula: $$Re = \frac{\rho vd}{\...
It is not possible to separate out the moment coefficient algebraically; this equation must be solved using an iterative technique for a given rotational Reynolds number. Equation 6.5 is restated in Equation 6.6, and a starting value of, say, Cmc = 0.02 generally results in a converged solution...

Reynolds Number can then be calculated using equation (1) likeRe = (910 kg/m3) (2.6 m/s) (25 mm) (10-3 m/mm) / (0.38 Ns/m2) = 156 ((kg m/s2)/N) = 156 ~ Laminar flow 1 (N) = 1 (kg m/s2) Related Mobile Apps from The Engineering ToolBox ...
输气管的雷诺数一般高达106~107,是输油管的10~100倍。The Reynolds number of the pipeline is generally as high as 106~107, which is 10~100 times that of the pipeline.
Reynolds Number, R: 1.00 × 105 Plate flow is transitioning to turbulent at a distance D from the leading edge. Pipe flow is fully turbulent in a pipe of diameter D. Equation Behind the Calculator The Reynolds Number is found from the equation, Glossary...
The dependence of the chaotic mixing of fluids on the Reynolds number Re in a partitioned-pipe mixer (PPM), composed of alternately placed horizontal and vertical plates in a rotating cylinder, is studied. By numerical simulations of the velocity field and fluid mixing, tubular transport barriers...
