... increased. (A way to test this is to hold a sheet of paper that is drooping and then blow along the paper, if done correctly the paper should rise) Bernoulli's Equation. The Bernoulli equation states that, but only when * point 1 and 2 lie on a streamline, * the fluid has a constant density, * the flow is steady * there is no friction. Although these restrictions sound severe, the Bernoulli equation is very useful, partly because it is very simple to use and partly because it can give great insight into the balance between pressure, velocity and elevation. Bernoulli's equation is the explanation for how an airplane is able to fly. It is an example of the first Law of Thermodynamics. In other words it states that Energy can not be created or destroyed. (Newtons Law) but it can be converted from one form to another. The question is how much air pressure difference is ...
