Medium Properties
Enter for the medium:
• longitudinal sound velocity (in m/s)
• kinematic viscosity (in mm
2
/s)
• density (in kg/m
3
)
• gas compressibility factor.
One to five values depending on the selected function have to be entered. Press ENTER
after each input.
If an already defined medium is edited, for each property of some of the functions will be
requested whether to edit it. Select YES or NO. Press ENTER. Change the values if nec-
essary.
14.3.4 Input of Heat Flow Coefficients
Select SPECIAL FUNCTION\INSTALL MEDIUM. Press ENTER.
Select YES to store the entered properties or NO to quit the
menu item without storing. Press ENTER.
Note! The heat flow coefficients can also be edited with the programs Flux-
Data and FluxKoef.
Note! The entered coefficients will not be checked. Absurd values can re-
sult in wrong measured values or in permanent system errors.
Select the list item HEAT-FLOW COEFFS. Press ENTER.
An error message will be displayed if the coefficient mem-
ory does not contain space for heat flow coefficients.
Partition the coefficient memory (see section 14.1).
Select the medium for which the heat flow coefficients
have to be entered.
User defined media will be displayed first, followed by the
media of the internal database.
Select an index for storing the heat flow coefficients of the
selected medium. Press ENTER.
If the coefficient memory is partitioned so that heat flow co-
efficients for two media can be entered, indices 01 and 02
are available.
