RE: Hazen William Formula

cckla,

Like you said, the Hazen William Formula is only used for liquid with similar properties as water at standard temperature, so if you have a liquid with different viscosity, then this formula is not applicable anymore.

I would suggest to use "Darcy-Weisbach-Colebrook Equation". It takes pipe roughness and viscosity into consideration, so it's more far ranging than any other formula I've used.

Regards,

ed

Subject: [PipingDesign] Hazen William Formula

Dear all specialists,

I understand that Hazen William formula is widely used for liquid with similar viscosity as water. If I would like to use this formula to estimate the head loss of a pipeline for more viscous liquid, is there any changes need to be done on the formula ? Please guide me.

Thanks.

Regards,
cckla
