Aerodynamic Drag Force Solution

STEP 0: Pre-Calculation Summary

Formula Used

Drag Force = Drag Coefficient*((Mass Density*Flow Velocity^2)/2)*Reference Area
F_drag = C_drag*((ρ*V_f^2)/2)*A_ref
This formula uses 5 Variables

Variables Used

Drag Force - (Measured in Newton) - Drag Force is the aerodynamic force that opposes an aircraft's motion through the air. Drag is generated by every part of the airplane.
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.
Mass Density - (Measured in Kilogram per Cubic Meter) - 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.
Flow Velocity - (Measured in Meter per Second) - 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.
Reference Area - (Measured in Square Meter) - The reference area A is typically the cross-sectional or frontal area of the object, but may also be the surface area (wetted area) or other representative area describing the object.

What is Aerodynamic Drag ?

Aerodynamic Drag is a force which the oncoming air applies on a moving body. It is the resistance offered by the air to the movement of the body. So, when a car is moving; it displaces the air. However, it affects the car’s speed and performance. Technically, it is the aerodynamic drag or the friction offered by the air to a vehicle.

How to Calculate Aerodynamic Drag Force?

Aerodynamic Drag Force calculator uses Drag Force = Drag Coefficient*((Mass Density*Flow Velocity^2)/2)*Reference Area to calculate 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 calculate Aerodynamic Drag Force using this online calculator? To use this online calculator 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. Here is how the Aerodynamic Drag Force calculation can be explained with given input values -> 1091.374 = 1.39*((98*1.77777777777778^2)/2)*5.07.
