Diameter at which turbulence starts Solution

Follow our step by step solution on how to calculate Diameter at which turbulence starts?

FIRST Step Consider the formula

D = {(\frac{5 \cdot 10^{5} \cdot u}{w})}^{\frac{1}{2}}

Next Step Substitute values of Variables

∴

D = {(\frac{5 \cdot 10^{5} \cdot 100St}{5rad/s})}^{\frac{1}{2}}

Next Step Convert Units

∴

D = {(\frac{5 \cdot 10^{5} \cdot 0.01m²/s}{5rad/s})}^{\frac{1}{2}}

Next Step Prepare to Evaluate

∴

D = {(\frac{5 \cdot 10^{5} \cdot 0.01}{5})}^{\frac{1}{2}}

Next Step Evaluate

∴

D = 31.6227766016838m

LAST Step Rounding Answer

∴

D = 31.6228m
