What is Drag Force?
In fluid dynamics, drag force is the resistance force exerted on an object moving through a fluid, such as air or water. The magnitude of this force depends on several factors, including the velocity of the object, the density of the fluid, and the object’s cross-sectional area.
Formula for Calculating Drag Force
The formula used for determining drag force on an object is given by:
Drag Force=0.5×Density of the Fluid×Velocity2×Cross-sectional AreaDrag Force=0.5×Density of the Fluid×Velocity2×Cross-sectional Area
Where:
- Drag Force: Represents the force acting against the direction of motion of the object (measured in Newtons, N).
- Density of the Fluid: Denotes the mass per unit volume of the fluid through which the object moves (measured in kilograms per cubic meter, kg/m³).
- Velocity: Signifies the speed of the object relative to the fluid (measured in meters per second, m/s).
- Cross-sectional Area: Refers to the area perpendicular to the direction of motion of the object (measured in square meters, m²).
