Flow Velocity given Rate of Flow through Propeller Solution

Follow our step by step solution on how to calculate Flow Velocity given Rate of Flow through Propeller?

FIRST Step Consider the formula

V f = (8 \cdot \frac{q flow}{π \cdot D^{2}}) - V

Next Step Substitute values of Variables

∴

V f = (8 \cdot \frac{24m³/s}{π \cdot {14.56m}^{2}}) - 6m/s

Next Step Substitute values of Constants

∴

V f = (8 \cdot \frac{24m³/s}{3.1416 \cdot {14.56m}^{2}}) - 6m/s

Next Step Prepare to Evaluate

∴

V f = (8 \cdot \frac{24}{3.1416 \cdot {14.56}^{2}}) - 6

Next Step Evaluate

∴

V f = -5.71171064528699m/s

LAST Step Rounding Answer

∴

V f = -5.7117m/s
