CORRECTED VOLUME FLOW CALCULATIONS
Gas English:
(PSIA/14.696) x (519.67/TEMP+459.67) x (1/Z) x UCFLOW = VOL
Where reference conditions = 60°F, 14.696 PSIA
Gas Metric:
(KPa/101.329) x (273.15/TEMP+273.15) x (1/Z) x UCFLOW = VOL
Where reference conditions = 0°C, 101.325 KPA
Liquid:
UCFLOW x [1-C x (Tf - Tref)]= VOL
MASS FLOW CALCULATIONS
UCFLOW x DENSITY = MASS
HEAT FLOW CALCULATIONS
Gas/Liquid English:
MASS x SH x (TEMP + 459.67) = HEAT
Gas/Liquid Metric:
MASS x SH x (TEMP + 273.15) = HEAT
Steam:
Specific Enthalpy x MASS = HEAT
Del Heat Liquid:
MASS x SH x (TEMP1 - TEMP2) = HEAT

6.5 K1 Factor Calculation

The K1 factor is used in Orifice/Pitot/Annubar calculations.
The K1 factor is the calibration factor for the meter run. It
is part of the Variables menu for flow input values (analog).
To calculate the factor take known conditions from calibra-
tion and apply them in the appropriate formula on the
following page to solve for K1.
available to assist in the computation of the K1 term.
