What is the equation for Water Expansion when ...

Hi all,

I know that water expands when heated above room temperature.

I just need to know what equations govern this expansion. For example, let's say I add x amount of heat, then water expands x amount.

Is it linear? Is there a maximum amount?

Any links on reading would help.

Coefficient of thermal expansion

Ok, I found this equation on wikipedia.

dV / Vo = 3*alpha* dT

T: temperature
V: Volume

It gives in a chart for water that 3*alpha is 207E-6 per C at 20 degrees C.

Does that mean that the change in volume (dV) will be 3*alpha*dT*Vo? That seems pretty linear.

The link here: http://www.plumbset.co.uk/waterexpansion.htm
gives a calculator for water expansion and the chart they give (if you click the link) looks nonlinear.

If I am trying to come up with a equation that gives me the amount of expansion if given the temperature what must I do.
