Question 2 1. The resistance to motion R for a sphere of diameter d moving at constant velocity u through a compressible fluid is dependent on the density p and the bulk modulus K. The resistance is primarily due to the compression of the fluid in front of the sphere. Show that the dimensionless relationship between these quantities is given by: Ne=(Ma)
