Question

Problem IV. (20 Points) A thin disk of diameter 0.5 m placed perpendicular to a wind flow of velocity 12 m/s at standard atmospheric conditions. (a) (15 Points) Calculate the drag force acting on the plate. (b) (5 Points) If the same plate is streamlined and the drag coefficient drops to 0.1, what is the percentage reduction in drag?

Step 1

The drag force ($F_D$) is given by: $$F_D = \frac{1}{2} \rho V^2 A C_D$$ where: - $\rho$ is the density of the fluid (air in this case) - $V$ is the velocity of the fluid - $A$ is the reference area - $C_D$ is the drag coefficient First, let's list the given Show more…
