Mass balance - Wikipedia

A mass balance, also called a material balance, is an application of conservation of mass to the analysis of physical systems. By accounting for material entering and leaving a system, mass flows can be identified which might have been unknown, or difficult to measure without this technique. The exact conservation law used in the analysis of the system depends on the context of the problem

8.Mass Balance - Food Loss and Waste Protocol

In a mass-balance calculation, an estimate of 90 metric tons (t) (±10 t) for the outputs is subtracted from 100 t (±10 t) for the inputs. In this simple example, there is no change in level of stock or in the weight of during processing. The resulting estimate of FLW would be 10 t (±14 t),assuming the only uncertainty emanates from that associated with the inputs and outputs. The

The effective variance weighting for least squares

The effective variance weighted least squares solution to the mass balance receptor model is derived from the theory of maximum likelihood. The solution is one which contains the effects of random uncertainties in both the receptor concentrations and the source compositions. The solution involves trancendental equations of the unknown source contribution variables, and an iterative solution is

MASS BALANCES - University of Washington

Mass balances help us answer questions about the rate at which pollutants accumulate in a system, the maximum concentration that a pollutant might reach at a point in a river following an upstream spill, or the size of a reactor that we have to build to achieve a desired percentage reduction in a pollutant’s concentration. These types of balances are useful in areas other than water

A dynamic Na/S balance of a kraft pulp mill

In the kraft mill the chemical balance is of interest to minimize the production cost. Normally there is an excess of sulfur and low levels of sodium, compared to what the process requires. In the future, the pulp mill will most likely produce other products than just pulp. These new production processes will also most likely affect the sodium and sulfur balance and there is a need to be able
