Question: 1. Show that for geometrically similar aerodynamic systems the nondimensional force coefficients of lift and drag depend only on Reynolds number and Mach number. Discuss briefly the importance of this theorem in wind-tunnel testing and simple performance theory.

2. "A pint's a pound the world around" is the old rhyme describing the weight of water. Given that a pint is an eighth of a gallon, which is 231.8 cubic inches, and the density of freshwater (not seawater) is 1.93 slugs per cubic foot, solve for the percentage error in the old rhyme.
