Question

Drag force is a function of______.

• A. Projeced area of the body
• B. Mass density of the fluid
• C. Velocity of the body
• D. All of the above

Answer 1

The correct option is D All of the above

$\text{Drag force,}{F}_D=C_D.\frac{\rho A{V}^2}{2}$

$A=\text{Projected area of body}$

$\rho =\text{Mass density of body}$

$V=\text{Velocity of the body}$

$C_D=\text{Coefficient of drag}$
