How to calculate the surface area of a finned tube?

[tiffanysmith]

I'm just wondering if there is an industry standard way of calculating the surface area of a finned tube? If not, can someone provide me with some formulas on how to calculate the surface area? Thanks!

Don't know but Google gave me this table as a first hit. :D

kindly check the tube manufacturers catalog where they will have specified multiplication factors for calculating the surface area values.
