No. That is form basic course. Proper course about fluid mechanics will be later. This is very simplified, but idea of this exercise is just learn how Bernoulli equation can be used in other situations than just pipes. And values of lifts and mass aren't real in my question.
We can do this: $$ v(bottom)^2 - v(top)^2 = (v(bottom) - v(top))*(v(bottom) + v(top))$$
so $$\Delta(v) = \frac {\Delta(v^2)}{v(bottom) + v(top)} $$
Value of $$\Delta(v^2)$$ we have, so we can calculate how v(bottom) depends on v(top)
$$ v(bottom) = \sqrt{\Delta(v^2) + v(top)^2}$$ And use this...
Homework Statement
We have a plane which lift area is A=500 m2 and weight of plane is m= 540 000 kg.
That the plane can stay in air the pressure difference between top and bottom of the lifts have to be:
B>G --> Δp= (m*g)/A = 10 594.8 Pa.
