Equation(5.16)is simply a modified form of Eqn(5.15)after performing conversions to commonly used pipeline units. R is still a dimensionless value. Another version of the Reynolds number in English units is as follows: (5.17)R=3,160Q/(νD) ...
— Reynolds number equation The Reynolds number formula depends on viscosity. We generally distinguish two types of viscosity: Dynamic viscosity μμ is a quantity that measures the force needed to overcome internal friction in a fluid. The units of dynamic viscosity are: Pa/sPa/s, N/(m²...
Thus, we return their units back to that of length by scaling: 𝐼∗1=𝐼1,I1∗=I1, (15) 𝐼∗2=(𝐼2)1/2,I2∗=I21/2, (16) 𝐼∗3=(𝐼3)1/3.I3∗=I31/3. (17) By applying the differential Gauss–Bonnet formula to the coordinate plane subfields of ...
