We will conduct a mass balance on the total riverwater mass. In this case, the ``concentration'''' of river water in mass/volume units is simply the density of the water, . where the term has been set to zero because we are ignoring chemical reaction. Since this is a steadystate problem, . Therefore, as long as the density is constant,, or . (b)

total mass of input = total mass of output. A material balance is an accounting for material. Thus, material balances are often compared to the balancing of current accounts. They are used in industry to calculate mass flow rates of different streams entering or leaving chemical or physical processes.
A coal preparation plant (CPP; also known as a coal handling and preparation plant (CHPP), coal handling plant, prep plant, tipple or wash plant) is a facility that washes coal of soil and rock, crushes it into graded sized chunks (sorting), stockpiles grades preparing it for transport to market, and more often than not, also loads coal into rail cars, barges, or ships.
Mass balance approach is a commonly used indirect method to study source contributions of pollutant loads into the receiving water bodies. This approach is useful especially when there are distinct dry and wet seasons as existent in the tropical countries like India. The mass balance .
