Upstream Velocity using Prandtl Relation Solution

Follow our step by step solution on how to calculate Upstream Velocity using Prandtl Relation?

FIRST Step Consider the formula

V 1 = \frac{{a cr}^{2}}{V 2}

Next Step Substitute values of Variables

∴

V 1 = \frac{{79.741m/s}^{2}}{79.351m/s}

Next Step Prepare to Evaluate

∴

V 1 = \frac{{79.741}^{2}}{79.351}

Next Step Evaluate

∴

V 1 = 80.1329168000403m/s

LAST Step Rounding Answer

∴

V 1 = 80.1329m/s
