Moisture Content of grain is usually determined on wet basis (wb), scientists sometimes use dry basis (db):
MCwb = Moisture content wet basis [%]
MCdb = Moisture content dry basis [%]
mi = Initial weight
mf = Final weight
Sometimes it is needed go convert from moisture content dry basis to moisture content wet basis.
During drying, paddy grain will loose weight due to loss of moisture:
Wi = Initial weight [g]
Wf = Final weight [g]
Example: 1000 kg of paddy is harvested at 25% MC, and dried down to 14% MC, what is the final weight of the dried grain?
Final weight of grain = 1000* (100-25)/(100-14) = 872 kg of paddy at 14 % MC
