Dear Sir:
I would like to know the physical properties of Naphtha (65 API).
Thanks

Which physical properties? What kind if naphtha? How accurate do the
numbers need to be? Etc.

SpGr =0.72, water =1.0
RVP = 18 psia
IBP = 0°F
50%BP =100°F
EP = 200°F
viscosity = 0.1 cP
Heat capacity = 0.45 BTU/Lb°F
Parafins = 77.8%
Olefins = 0.2%
Naphthenes = 7%
aromatics = 15%

Dear Sir:
First of all, I would like to thank you about your replay.
About the Naphtha physical properties I would like to know the specific heat
(Cp) density formula .
I need these information in designing a shell and tube heat exchanger.

The number for Cp posted by Calmonetwo of 0.45 BTU/lb F appears
reasonable for HtX calcs. Remember that the fouling factor will be very
dependent on the 'source' of the naphtha. Cracked Naphtha (from a Coker
or FCC) will generally have a much greater fouling factor than say
virgin naphtha.

you can find these in API data book,Maxwell data book and TEMA hand book

hurmm.. what about its heat of formation?
