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:
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.
