Drag Force as per Stokes Law Solution

Follow our step by step solution on how to calculate Drag Force as per Stokes Law?

FIRST Step Consider the formula

F D = 3 \cdot \frac{D S}{π \cdot μ viscosity \cdot V s}

Next Step Substitute values of Variables

∴

F D = 3 \cdot \frac{128m}{π \cdot 10.2P \cdot 1.5m/s}

Next Step Substitute values of Constants

∴

F D = 3 \cdot \frac{128m}{3.1416 \cdot 10.2P \cdot 1.5m/s}

Next Step Convert Units

∴

F D = 3 \cdot \frac{128m}{3.1416 \cdot 1.02Pa*s \cdot 1.5m/s}

Next Step Prepare to Evaluate

∴

F D = 3 \cdot \frac{128}{3.1416 \cdot 1.02 \cdot 1.5}

Next Step Evaluate

∴

F D = 79.8895400618141N

LAST Step Rounding Answer

∴

F D = 79.8895N
