Bernoulli principle has many applications like airplanes take off etc. But when we apply Bernoulli's principle we dont refer the reference frame in which we measure the velocity of air for example. Same happens with magnus effect. Does Bernoulli's principle (equation) apply for all reference frames?

Interesting article: short answer is "no" http://www.physics.princeton.edu/~mcdonald/examples/bernoulli.pdf – Daddy Kropotkin Dec 24 '18 at 21:11

thanks but then how we know when to apply the bernoullis principle ? – Antonios Sarikas Dec 24 '18 at 21:32

The principle is frame-dependent, so it's only applicable in certain frames of reference relative to a moving fluid: i.e. inertial frames. – Daddy Kropotkin Dec 24 '18 at 22:56
