Final answer:
Dynamic lift in an airplane is calculated using Bernoulli's Principle, which correlates the speed of airflow over the wing with pressure differences that create upward lift, crucial in aircraft design.
Step-by-step explanation:
The dynamic lift on an airplane is primarily calculated using Bernoulli's Principle, which states that an increase in the speed of a fluid occurs simultaneously with a decrease in pressure or a decrease in the fluid's potential energy. When air flows over a wing, it moves faster over the longer upper surface, creating lower pressure on top compared to the bottom.
This pressure difference generates lift. The ideal lift required by an aircraft's wing can be calculated using Bernoulli's equation, taking into account factors like air density and velocity. For example, to maintain a lift of about 1000 N per square meter, as noted in aircraft design, the velocity of the air over the wing's upper surface must be manipulated based on conditions such as air density and plane speed.
