Question details

ANSWER ALL PARTS

Benzene Evaporation (Fick’s Law)

An open tank, 10 ft in diameter, contains benzene at 25°C that is exposed to air. Above the liquid benzene surface is a stagnant air film 1.00 in thick. If the pressure is 1 atm and the air temperature is 25°C what is the loss of benzene from the tank (through vaporization and diffusion into the air) in lbs/day?

Specific data and assumptions:

Specific gravity of benzene at 60°F = 0.875

Benzene vapor pressure at 25°C is 105 mmHg (Note: Check / Confirm this value)

Diffusivity (Benzene in air) at 25°C is 0.08 cm2 /s (Note: Check / Confirm this value)

The concentration of benzene (above) the stagnant air is negligible (~zero)

How accurate is the solution based on the assumed values provided? Compare with improved/confirmed values found? (Provide refs for sources, methods employed)
