Bernoulli derived the equations that are used today to describe the motion of fluids. The link below gives an good overview.

Bernoulli's Equation
The Bernoulli equation states that,
P + (rho)*V^2 + (rho)*g*h = constant
where
points 1 and 2 lie on a streamline,
the fluid has constant density,
the flow is steady, and
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.

Or maybe not so techy.
flow rate =pipe area x velocity
velocity is the speed at which a chunk of fluid is moving past a given point. Usually measured in feet per second.
v=q/a

The Navier-Stokes equations.
The Bernoulli equation is for the special case of laminar (non-turbulent) flow.

A detailed model of a uncompressible fluid is given by Euler's equations,
dx/dt + x du/dx + dp/dx = 0
dy/dt + y dv/dy + dp/dy = 0
dz/dt + z dw/dz + dp/dz = 0
du/dx + dv/dy + dw/dz = 0
where d stands for partial derivative, (u,v,w) for velocity and p for pressure.

exactly how long it's been since you last peed ...plus.... the amout of fluids consumed in that period...divided by..the size of your bladder....multiplied by.... the distance to the nearest restroom.....squared by Pi.....didn't you know that???
