 the point is equation okay one more update have you seen that that is so the air rushes outside it takes some fluid also along with it so that is out itself they have the planes they burn on what is actually what it is actually oxygen and how the heart gets the same thing inside the heart yeah this is very serious you will fall flat you used to be around you might get to move forward it didn't so it will go straight no change so now forces will be unbalanced so there will be a neck force acting in this way force because of the combs in the air you don't know have you learned such that it generates a force which balances the weight of the inside the wing you store the fluid so you store the having a separate tank to store the wing itself but that is none of our concern when it comes to study fluid dynamics here but still fixed in the space it is a wing that is moving so we will go minus P2 into L and see what what a huge aircraft will be in a hangar what kind of a logic so here is the question advance okay we will have a question 500 mean 960 kms 6.68 to 10 is 0.06% of the atmosphere difference should be there also sitting here you are done with fluid dynamics it's not so easy right it is in the speed of the air on the upper surface 6.5, 6.5 in the book it is 6.5 anyways whatever it is it will be just 8% sufficient
