Assume that the drag force (Fa) exerted by a flowing fluid on a body is a function of density (p), dynamic viscosity coefficient (u) and velocity of the fluid (u), and a characteristic length of the body (L). Using dimensional analysis, show that Fa = Ca p A u?/2, where 'Ca' is drag coefficient and 'A' is characteristic area of the body. %3!
