Hi,
I am currently verifying a line size for the replacement of a hot seawater line operating at 8 barg and 65 C. We are using an Elastopipe with a hazen Williams C-factor of 130. Using the Hazen-Williams equation has some disadvantage in my case given that the temperature is outside the applicable range of the equation (up to 24 C).
If the vendor doesn't provide a roughness value, Is there a way to calculate it using the C-factor?
Thanks,
Sherif
