WebThe authors propose an equation for estimating the discharge coefficient in practical applications. This equation balances the number of terms (three dimensionless coefficients) and accuracy (R 2 = 98 %). Although it is dimensionless, the correlation must be used within the established ranges of values to ensure its effectiveness: Reynolds ... WebDrag coefficient vs. particle Reynolds number of nonspherical particles (experimental data). ... The flow Reynolds number VD H /v equals 1.5 × 10 3 and the shear Reynolds number of the flow k s V * /v equals 25.7. The flow is turbulent in the transition (between smooth and fully rough). Hence, the above calculation of the Darcy friction factor ...
WebFeb 26, 2011 · 688. 1. The dependence of flow coefficient and Reynold's Number is strong when the flow is layared (i.e. laminar) and in the "transition" region between Re of …
