This list is provided as an example. Additional liquids are being
added continuously. Select the appropriate liquid from the list
or select OTHER if the liquid is not listed.
FLUID SS -- Speed of Sound in the Fluid
ENGLSH (Feet per Second)
METRIC (Meters per Second)
Allows adjustments to be made to the speed of sound in the liq-
uid. If the UNITS value was set to ENGLSH, the entry is in FPS
(feet per second). METRIC entries are made in MPS (meters
per second).
If a fluid was chosen from the FL TYPE list, a nominal value for
speed of sound in that media will be automatically loaded. If the
actual sound speed rate is known for the application fluid and
that value varies from the automatically loaded value, the value
can be revised.
If OTHER was chosen as FL TYPE, a FLUID SS will need to be
entered. A list of alternate fluids and their associated sound
speeds are located in the Appendix at the back of this manual.
FLUID VI -- Absolute Viscosity the Fluid
cps
Allows adjustments to be made to the absolute viscosity of the
liquid.
If a fluid was chosen from the FL TYPE list, a nominal value for
viscosity in that media will be automatically loaded. If the actual
viscosity is known for the application fluid and that value varies
from the automatically loaded value, the value can be revised.
If OTHER was chosen as FL TYPE, a FLUID VI will need to be
entered. A list of alternate fluids and their associated viscosities
are located in the Appendix at the back of this manual.
