drums of dimensions ( height=6.5 ft and diameter of 1.2 ft) are being filled with certain chemicals ( Mw=118 g/mole). the containers are being splash filled at the rate of 0.5 drums per minute. the opening through which the containers are being filled has as area of 8 cm^2. the vapor pressure of the chemicals is 0.6 mm Hg under these conditions.

Assume extremely poor mixing.

a) estimate the ambient vapor concentration (ppm) if the ventilation rate is 100 ft^3/min.

b) suggest proper practical ways to reduce the concentration.
