3-13. Two liters of a liquid chemical is spilled on the laboratory floor. Assume 1 atm of pressure and a temperature of 25C 3. If the liquid pool is 2mm deep, calculate the area of the pool. 4. What ventilation rate, in m3/s, is required to prevent the air concentration from exceeding the TLV for the chemical of 100ppm ? 5. Ventilation air is provided for the lab via a 0.5-m-square duct. The air velocity exiting the duct is measured with a velometer at 30m/s. Calculate the volumetric flow of air from this duct in m3/s. Is this adequate ventilation for this spill? Data for the liquid chemical: - Molecular weight: 100 - Saturation vapor pressure of chemical at 25C:100mmHg
