C is calculated from the following equation:
C = % residual moisture = (Psat/14.696) * 100%
Psat (saturated pressure) determined from Saturated Water - Temperature table
knowing the vortex cooler temperature. A regression was performed from the look-
up table data for temperatures from 0°C to 32.2°C (32°F to 90° F). The resulting
function is sued in the Humox software to calculate the residual moisture.
C = % residual moisture = 0.63e(.064 * Cooler Temperature in C)
The wet and dry O

(% by Volume) are calculated using the following Nernst equa -
tions:
% O
2
wet = 20.9% O
2
wet / 10 (wet cell mV/AT)
% O
2
dry = 20.9% O
2
dry / 10 (dry cell mV/AT)
AT - Cell logarithmic slope (ideally 48 mV per decade for T = 695°C)
A - Constant (.0496 mV/decade/°K)
T - Temperature (°K)(°C + 273)
