## Main Question or Discussion Point

Hello Physics Masters!

I would like to calculate pressure drop values caused by friction as water flows through a a smooth pipe at different velocities and different internal pipe diameters.

I ONLY want the pressure drop values caused by friction, not the pressure drop values caused by Bernoulli's principle. The mathematical formulas that I have found combine Bernoulli's principle PLUS friction. I only need the friction component.

Can you direct me to a web site that would have this information, or provide the friction-only mathematical formula?

Thanks,

Roger
