The quantity of heat produced during combustion is thus lower than the gross calorific value, as the water vaporisation heat is not recovered. The net calorific value(NCV)” is calculated by subtracting from the GCV the water vaporisation heat.
The energy values measured in the calorimeter are thus generally higher than those listed on the food identification label, because these figures describe the value that is actually released from the organism–the so-called physiological energy value. Physiological energy value.
