as - ✔✔Flow separation

The standard atmospheric values are... - ✔✔15C 59F 29.92
Bernoulli's principle would show: - ✔✔A decrease in the speed of flow would cause an increase in the
fluid's static pressure
What affects total lift production? - ✔✔The net effect of airflow around the airfoil
The following is a practical application of the Bernoulli's theorem: - ✔✔
Vortex generators increase the lift by - ✔✔Adding kinetic energy to the boundary layer
