SUMMARY
This discussion focuses on calculating the drag force on a smooth cylinder using pressure distribution data obtained from a wind tunnel. The user collected pressure measurements in inches of water at various angles around the cylinder, along with known freestream velocity and stagnation pressure. By determining the pressure coefficient (Cp) at each measurement point and integrating the product of Cp and the cosine of the angle of rotation from 0 to π, the user successfully calculated drag coefficients of 0.71 for the large cylinder and 1.07 for the small cylinder.
