11.3 Calculation methods
Humidity may be calculated upon the basis of various mathematic formulas, defined in
balance – drier as Calculation method:
1. Relative humidity, defined in relation to initial mass
w [%] = m
0
-m/m
0
*100% ,
where m
0
– initial mass, m- current mass
2. Relative humidity, defined in relation to current mass
w [%] = m
0
-m/m*100% ,
3. Percent current mass content in sample
w [%] = m/ m
0
*100% .
Drying temperature is maximum temperature, measured by sensor, located in the dried
material vicinity. Note that the dried material temperature may be higher than its
surrounding temperature.
