Please Provide Full Working, Thank You!
(b) A stationary sphere in glycerin of density 1260 kg/m² moving at a velocity of 1.8 m/s experiences a drag of 6N. Another sphere of thrice the diameter is placed in a wind tunnel. The ratio of kinematic viscosities of air and glycerin is 15, and the density of air is 1.28 kg/m² Determine the velocity of the air and the drag which will give dynamically similar conditions.
