Bernoulli's Principle says _____.

• “As a fluid’s speed increases, the pressure within the fluid decreases.”

• “As a fluid’s speed increases, the pressure within the fluid increases.”

• “As a fluid’s speed decreases, the pressure within the fluid increases.”

• “As a fluid’s speed decreases, the pressure within the fluid decreases.”

What part of the airfoil meets the relative wind first? ______________________________________________
