APPENDIX B: FLUID PROPERTIES
B.1 Fluid Sound Velocities & Kinematic Viscosities
This section 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).
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.
