Mass balance calculations can use the depiction of a flowsheet in two ways. Simple calculations should superimpose the calculation cells directly over the flowsheet, as in example calc 1. More complicated calcs should use the flowsheet to define stream numbers and then perform the computations in a table, as in example calc 2. Ball Mill Example 1
