SOLVED:A classroom having a volume of 283 m^3 undergoes 1.5 air changes per hour from natural ventilation. The concentration of carbon dioxide in the outside air is 0.03 per cent and the production of carbon dioxide per person is 4.72 ×10^-6 m^3 s^-1 (a) What is the maximum occupancy of the space if the carbon dioxide concentration is to be less than 0.1 per cent at the end of the first hour, assuming an initial concentration equal to the ambient outside conditions? (b) What is the maximum occup
