Outlet Diameter of Impeller using Speed Ratio, Manometric Head and Impeller Speed Solution

Follow our step by step solution on how to calculate Outlet Diameter of Impeller using Speed Ratio, Manometric Head and Impeller Speed?

FIRST Step Consider the formula

D 2 = \frac{84.6 \cdot K u \cdot \sqrt{H m}}{ω}

Next Step Substitute values of Variables

∴

D 2 = \frac{84.6 \cdot 0.85 \cdot \sqrt{25.3m}}{179.07rad/s}

Next Step Convert Units

∴

D 2 = \frac{84.6 \cdot 0.85 \cdot \sqrt{25.3m}}{1709.9925rev/min}

Next Step Prepare to Evaluate

∴

D 2 = \frac{84.6 \cdot 0.85 \cdot \sqrt{25.3}}{1709.9925}

Next Step Evaluate

∴

D 2 = 0.211521897467202m

LAST Step Rounding Answer

∴

D 2 = 0.2115m
