Calculation of the particle number concentration in a classroom

Input parameters
To compare different cases, check Case 1, 2, 3 boxes first and enter the conditions of Case 1, Case 2 and Case 3 seperately. When finished, push Calculate to get the comparison curves. For comparison of 2 cases, check only Case 1, 2 boxes.
