    They're the same.

    Torque on a point on a sphere in a fluid/finding pressure?

    drag = 1/2 ρf v^2 Cd A where pf is the fluid density, v is the velocity of the sphere, Cd is the drag coefficient for the sphere (0.1 for smooth, 0.6 for rough) and A is the reference (cross-sectional) area

    Torque on a point on a sphere in a fluid/finding pressure?

    If there is a rotating sphere (falling through a fluid) a) is the torque the same at every point on the sphere's surface, and b) how would I use said torque to work out the pressure exerted by opposite 'sides' of the sphere on the fluid? Homework Equations The Attempt at a Solution
