What is the primary principle behind Bernoulli's equation in aerodynamics?
A. The pressure of a fluid decreases as its velocity increases
B. The pressure of a fluid increases as its velocity increases
C. The fluid density remains constant
D. The fluid velocity increases with altitude
Explanation:
Bernoulli’s equation states that the pressure of a fluid decreases as its velocity increases, which is a fundamental concept in aerodynamics for explaining lift on wings.
