Bernoulli’s Theorem:

TOTAL PRESSURE of a fluid remains CONSTANT when set in motion While the total pressure remains unchanged, STATIC PRESSURE DECREASES when there is an increase in fluid velocity

PTOTAL = PSTATIC + PDYNAMIC

what creates lift—Bernoulli and Newton share the credit, with Newton holding a slight edge. The bottom line is that there must be a net positive pressure difference between the top and bottom of the lifting surface.
