Appendix B
Fluid Properties
This appendix provides a table of fluid sound speeds and kinematic
viscosities. The information is based on material from the
Cameron
Hydraulic Data Book (17th ed., Ingersoll-Rand, 1988) and Table of Physical
and Chemical Constants (13th ed., Longmans, 1966).

Viscosities
Note that viscosity does not have as significant an effect on flow accuracy as
sound speed since viscosity is only used to calculate flow profile. Even a
comparatively large error in viscosity results in a change of only 2 to 5
percent.
