Bernoulli's equation

Finding out the pressure of water in a pipe can be extremely hard and tiring, but it can even harder to find out the pressure of more than one place in the pipe! However one can actually easily do this with an equation! With bernouilli's equation "p+1/2pv^2+pgh", which is constant for any two points in a pipe or any other water filled container, one can easily find out the balance between pressure, velocity, and height, and therefore, easily find out the pressure. With this one equation, one can also learn that as area increases, pressure decreases! This equation and many others that involves physics or other math-related subjects, one can understand the world more deeply. This shows that a single equation can be extremely useful and versatile.
