An open circular tank 8 m in diameter contains n-propanol at 25°C exposed to the atmosphere in such a manner that the liquid is covered with a stagnant air film estimated to be 5 mm thick. The concentration of propanol beyond the stagnant film is negligible. The vapor pressure of propanol at 25°C is 20 mm Hg. If propanol is worth $1.20 per liter, what is the value of the loss of propanol from this tank in dollars per day? The specific gravity of propanol is 0.80. Note: The diffusivity can be corrected for temperature using the temperature correction from the Chapman-Enskog equation.

Question
An open circular tank 8 m in diameter contains n-propanol at 25°C exposed to the atmosphere in such a manner that the liquid is covered
with a stagnant air film estimated to be 5 mm thick. The concentration of propanol beyond the stagnant film is negligible. The vapor pressure of propanol at 25°C is 20 mm Hg. If propanol is worth $1.20 per liter, what is the value of the loss of propanol from this tank in dollars per day? The specific gravity of propanol is 0.80.
Note: The diffusivity can be corrected for temperature using the temperature correction from the Chapman-Enskog equation.
