Learn how to calculate the drag force experienced by an object moving through a fluid using the drag equation, which depends on the fluid density, velocity, reference area and drag coefficient. The drag coefficient varies with the Reynolds number and the Mach number for gases, and can be derived by dimensional analysis.
Definition: DRAG FORCE. Drag Force \(F_D\) is found to be proportional to the square of the speed of the object. Mathematically \[F_D\propto v^2 \] \[F_D = \dfrac{1}{2} C_{\rho} Av^2, \] where \(C\) is the drag coefficient \(A\) is the area of the object facing the fluid, and \(\rho\) is the density of the fluid.
