Flow Velocity of Section Solution

Follow our step by step solution on how to calculate Flow Velocity of Section?

FIRST Step Consider the formula

V f = (V mean \cdot \frac{R}{w}) - \frac{0.5 \cdot dp|dr \cdot (D \cdot R - R^{2})}{μ}

Next Step Substitute values of Variables

∴

V f = (10.1m/s \cdot \frac{4m}{2.29m}) - \frac{0.5 \cdot 17N/m³ \cdot (2.9 \cdot 4m - {4m}^{2})}{10.2P}

Next Step Convert Units

∴

V f = (10.1m/s \cdot \frac{4m}{2.29m}) - \frac{0.5 \cdot 17N/m³ \cdot (2.9 \cdot 4m - {4m}^{2})}{1.02Pa*s}

Next Step Prepare to Evaluate

∴

V f = (10.1 \cdot \frac{4}{2.29}) - \frac{0.5 \cdot 17 \cdot (2.9 \cdot 4 - 4^{2})}{1.02}

Next Step Evaluate

∴

V f = 54.3085880640466m/s

LAST Step Rounding Answer

∴

V f = 54.3086m/s
