To calculate the drag force of an object moving through a fluid use the formula:
Fd = 1/2 * ρ * u² * A * Cd
Where ρ is the liquid density, u is the relative velocity, A is the reference area and Cd is the drag coefficient.
How do you calculate drag on a car?
To calculate the aerodynamic drag force acting on a vehicle while moving, use the formula:
Fad = 1/2 * ρair * u² * A * Cd
Where ρair is the air density, u is the relative velocity, A is the cross-section area of the vehicle and Cd is the aerodynamic drag coefficient.
What is a drag coefficient
The drag coefficient (Cd) is a dimensionless quantity that is used to quantify the drag or resistance of an object as it moves through a fluid environment. It depends on the shape of the object.
What is drag force?
The drag force is a force acting in a direction opposite to the relative motion of any object moving through a fluid like air and water.
