WebThe Reynold's Number is a unitless, dimensionless quantity. Knowing the Reynold's Number gives you a way to predict what's the first speed where you might expect turbulence, and therefore the first speed where you might expect Poiseuille's Law to not give you an accurate description of the flow of the fluid. Up next: video. WebThe Reynolds number inside the fuel channel is equal to: ReDH = 5 [m/s] x 0.01 [m] / 0.12×10 -6 [m 2 /s] = 416 600 This also fully satisfies the turbulent conditions. Reynolds Number and External Flow The Reynolds number describes the external flow naturally as well.
