Velocity Gradient Solution

Follow our step by step solution on how to calculate Velocity Gradient?

FIRST Step Consider the formula

dvdy = \frac{dv}{dy}

Next Step Substitute values of Variables

∴

dvdy = \frac{10.1m/s}{1000mm}

Next Step Convert Units

∴

dvdy = \frac{10.1m/s}{1m}

Next Step Prepare to Evaluate

∴

dvdy = \frac{10.1}{1}

Next Step Evaluate

∴

dvdy = 10.1Hz

LAST Step Convert to Output's Unit

∴

dvdy = 10.1cycle/s
