# How can I calculate viscosity of water at different temperatures?

The rate of flow of a liquid through a pipe at a given temperature is:

R =

Where p = pressure

a = radius of pipe

l = length of pipe

You would need to measure the rate of flow of water through a pipe of known length and radius at different temperatures at a constant pressure.

The coefficient of viscosity =

This will be for a particular value of T.

You would then repeat for different values of T.
