Rate of Flow through Propeller Solution

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

FIRST Step Consider the formula

Q = (\frac{π}{8}) \cdot (D^{2}) \cdot (V + V f)

Next Step Substitute values of Variables

∴

Q = (\frac{π}{8}) \cdot ({14.56m}^{2}) \cdot (6m/s + 5m/s)

Next Step Substitute values of Constants

∴

Q = (\frac{3.1416}{8}) \cdot ({14.56m}^{2}) \cdot (6m/s + 5m/s)

Next Step Prepare to Evaluate

∴

Q = (\frac{3.1416}{8}) \cdot ({14.56}^{2}) \cdot (6 + 5)

Next Step Evaluate

∴

Q = 915.746612506073m³/s

LAST Step Rounding Answer

∴

Q = 915.7466m³/s
