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 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 ...
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}{\...

TheColebrook-White equationis used to calculate the friction factor for turbulent flow. The friction factor is then used in the Darcy-Weisbach formula to calculate the fluid frictional loss in a pipe.
The rotational Reynolds number for the shaft, from Equation 4.1, is Reφ=ρΩb2μ=5.2×1571×0.0623×10−5=9.80×105 This value is significantly higher than 60, so the flow can be taken to be turbulent. Assuming an initial guess for the moment coefficient in Equation 6.6 of Cmc = 0.02...
