Problem 6.55 [2] Given: Air flow over a wing Find: Air speed relative to wing at a point Solution: Basic equation p ρ V 2 2 + gz + const = p ρ R T = Assumptions: 1) Incompressible flow 2) Inviscid 3) Steady 4) Along a streamline Hence, applying Bernoulli between the upstream point (1) and the point on the wing (2) p 1 ρ V 1 2 2 + p 2 ρ V 2 2 2 + = where we ignore gravity effects Hence V 2 V 1 2 2 p 1 p 2 () ρ + = For air ρ p RT = ρ
