What is mass balance formula?
What is mass balance formula?
Mass balance equation simply states that total mass in any system is always conserved. That is, Total mass in = Total mass out + Total mass accumulated in the system. The mass balance can be performed for different components of the inlet and outlet streams.
What is positive mass balance?
If the mass of snow accumulated on a glacier exceeds the mass of snow and ice lost during summer months, the mass balance is positive.
What is net mass balance?
A glacier’s net mass balance is a single figure that describes volumetric change across the entire glacier across the full balance year.
What is geodetic mass balance?
Geodetic methods are an indirect method for the determination of mass balance of glacier. Maps of a glacier made at two different points in time can be compared and the difference in glacier thickness observed used to determine the mass balance over a span of years.
What is negative mass balance?
If the mass of snow accumulated on a glacier exceeds the mass of snow and ice lost during summer months, the mass balance is positive. Likewise, if summer melting exceeds what was gained in the previous winter, the mass balance of the glacier is negative.
What is a mass balance model?
Mass balance models are deterministic models, derived from understanding of the underlying physical processes that govern transfers and transformations of pollutants in the environment.

What is the mass balance for the surface and deep layer?
The mass balance for and element in the surface layer is: Vmix {d[Csurf]/dt} = R [Criver] – Vmix ([Cs] – [Cd]) – P The mass balance for the deep layer is: Vmix {d[Cdeep]/dt} = Vmix ([Cs] – [Cd]) + P – B At steady state we have: d[C]/dt = 0 and R[Criver] = B Two important properties that are derived from the two box model
