FLOW INPUT CALCULATIONS:
Digital:
(Hz/K) x (60 sec/1 min) = UCFLOW
Analog-Linear:
Lo-Flow + (Hi Flow – Lo Flow) x (%) = UCFLOW
Analog-Orifice/Pitot:
Delta P lo + (Delta P hi – Delta P lo) x (%) = DP
DENSITY CALCULATIONS:
Density-Liquid:
SG x 62.3663 = DENSITY (Metric: SG x 62.42797 =
DENISTY)
Density-Steam:
1/SV = DENSITY
Density-Gas English:
(2.698825 x SG x PSIA)/(Z x TEMP + 459.67) = DENSITY
Density-Gas Metric:
(3.483407 x SG x kPa)/(Z x TEMP + 273.15) = DENSITY
Orifice/Pitot Calculation English:
K1 x
√DP/(DENSITY x 0.3705316202) = UCFLOW (in
ACFM)
Orifice/Pitot Calculation Metric
K1 x
√DP/(DENSITY x 0.287075) = UCFLOW (in m 3
/h)
VOLUMETRIC FLOW CALCULATIONS:
Gas English:
(PSIA/14.696) x (519.67/TEMP + 459.67) x (1/Z) x
UCFLOW) = VOL
Gas Metric:
(PSIA/14.696) x (273.15/TEMP + 273.15) x (1/Z) x
UCFLOW) = VOL
Liquid:
UCFLOW x [1-C x (TEMP – BR)] = VOL
MASS FLOW CALCULATIONS:
Gas/Steam:
UCFLOW x DENSITY = MASS
Liquids English:
[1-C x (TEMP – BR)]
2
x DENSITY x UCFLOW = MASS
Liquids Metric:
[1-C x (TEMP – BR)]
2 x DENSITY x UCFLOW = MASS
HEAT FLOW CALCULATIONS:
Gas/Liquid:
MASS x SH x (TEMP + 459.67) = Heat
Steam:
SH x MASS = HEAT
Del Heat Liquid:
MASS x SH x (TEMP
1
– TEMP
2
) = HEAT
