As a result, material balance closure to within 5% for material balances for most industrial processes is considered reasonable. Closure is defined as the calculated difference between the amount of a particular material entering and exiting the process divided by the amount entering multiplied by 100. If special attention is paid to ...
The Material Balance Equation Derivation Several of the material balance calculations require the total pore volume (P.V) as expressed in terms of the initial oil volume N and the volume of thegas cap. The expression for the total pore volume can be derived by conveniently introducing the parameter m into the relationship asfollows.
