Unformatted text preview: ρ p F p = ρ m F m 2.76(b): We are given H p = 12 H m . Also, the densities are ρ p = 0.00234 slug/ft 3 and ρ m = 0.00585 slug/ft 3 . So, the velocity ratio is U m U p = ρ p ρ m H p H m = X . 00234 slug / ft 3 . 00585 slug / ft 3 ~ (12) = 4 . 8 Since the speed for flow past the model is given to be 240 ft/sec, we find U p = U m 4 . 8 = 50 ft sec Also, the force on the model is 70 lb, so that F p = F m ρ m ρ p = (70 lb) X . 00585 slug / ft 3 . 00234 slug / ft 3 ~ = 175 lb...
