Speciestheprimary
compensating rate.
STB 103 Coef A2 Temperature Coef A2
Speciesthesecondary
compensating rate.
The density correction calculation can be set using the following procedure.
(1) Settotheuseofthetemperature-correcteddensitybyreferringtoSubsection5.1.9.
(2) Setthefunctionoftheexternaltemperatureinputfunctiontothetemperaturebyreferringto
Section 5.4.
(3) SettherangehighlimitandlowlimitoftheexternaltemperatureinputbyreferringtoSection
5.4.
(4) SetthestandardtemperatureandstandarddensitybyreferringtoSubsections5.1.9and
5.1.10.
(5) Settheprimaryandsecondarycompensatingratesofthecompensationformula.
NOTE
Thedensitycorrectioncalculationisperformedonlywhenitems(1)and(2)abovearespecied.
Iftheyarenotspecied,thedensityisassignedtothexedvaluethatisspeciedinSubsection
5.1.9.
Example:
If the water density is corrected based on the temperature in the following conditions, the result is
obtained as shown below.
