Problem 3-13. Two liters of a liquid chemical is spilled on the laboratory floor. Assume 1 atm, 25
a. If the liquid pool is 2 mm deep, calculate the area of the pool.
b. What ventilation rate, in m3/s, is required to prevent the air concentration from exceeding the TL
for the chemical of 100 ppm?
c. 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 30 m/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 25
C: 100 mm Hg
Solution to Problem 3-13
a) Area if pool with depth of 2 mm
b) Ventillation rate in m3/s
