Q (3). A sphere is held in as mall wind tunnel where air at 37.8C and 1atm abs and various velocities is forced by the sphere having a diameter of 0.042m. (a) Determine the drag coefficient and force on the sphere for a velocity of 2.30104m/s. Use Stokes' law here if it is applicable. (b) Also determine the force for velocities of 2.30103,2.30102,2.30101, and 2.30 m/s. Make a plot of FD versus velocity. Q (3).
