Aerodynamic Drag Force Solution

Follow our step by step solution on how to calculate Aerodynamic Drag Force?

FIRST Step Consider the formula

F drag = C drag \cdot (\frac{ρ \cdot {V f}^{2}}{2}) \cdot A ref

Next Step Substitute values of Variables

∴

F drag = 1.39 \cdot (\frac{98kg/m³ \cdot {6.4km/h}^{2}}{2}) \cdot 5.07m²

Next Step Convert Units

∴

F drag = 1.39 \cdot (\frac{98kg/m³ \cdot {1.7778m/s}^{2}}{2}) \cdot 5.07m²

Next Step Prepare to Evaluate

∴

F drag = 1.39 \cdot (\frac{98 \cdot {1.7778}^{2}}{2}) \cdot 5.07

Next Step Evaluate

∴

F drag = 1091.37445925926N

LAST Step Rounding Answer

∴

F drag = 1091.3745N

Formulas to find Drag Force

Drag Coefficient

Drag Coefficient is a dimensionless quantity that is used to quantify the drag or resistance of an object in a fluid environment, such as air or water.

Symbol: C_drag

Measurement: NAUnit: Unitless

Note: Value should be greater than 0.

Formulas to find Drag Coefficient

Mass Density

Mass Density is a representation of the amount of mass (or the number of particles) of a substance, material or object in relation to the space.

Symbol: ρ

Measurement: Mass ConcentrationUnit: kg/m³

Note: Value should be greater than 0.

Formulas to find Mass Density

Flow Velocity

Flow Velocity is the vector field that is used to describe fluid motion in a mathematical manner. The entire length of the flow velocity is referred to as the flow speed.

How to Evaluate Aerodynamic Drag Force?

Aerodynamic Drag Force evaluator uses Drag Force = Drag Coefficient*((Mass Density*Flow Velocity^2)/2)*Reference Area to evaluate the Drag Force, The Aerodynamic Drag Force equation states that drag force is equal to the drag coefficient times the mass density times half of the flow velocity squared times the reference area. Drag Force is denoted by F_drag symbol.

How to evaluate Aerodynamic Drag Force using this online evaluator? To use this online evaluator for Aerodynamic Drag Force, enter Drag Coefficient (C_drag), Mass Density (ρ), Flow Velocity (V_f) & Reference Area (A_ref) and hit the calculate button.

FAQs on Aerodynamic Drag Force
