A small diameter tube closed at one end was filled with benzene
to within 20 mm from the top of the tube and maintained at 295 K
and atm pressure of 100 kPa with a gentle stream of air blowing
across the top. After 30 kilo-seconds (30 x 103 s) the liquid level
has fallen to 25.8 mm. The vapor pressure of benzene at 295 K is
13.3 kPa. Calculate the diffusivity of benzene in air. Density of
benzene = 800 kg/m3. Molecular weight of benzene = 78 kg/kg
mol.

A thin-walled tube with a diameter of 6 mm and length of 20 m is
used to carry exhaust gas from a smoke stack to the laboratory in a
nearby building for analysis. The gas enters the tube at 200°C and
with a mass flow rate of 0.001 kg/s. Autumn winds at a temperature
of 15°C blow directly across the tube at a velocity of 7 m/s.
Assume the thermophysical properties of the exhaust gas are those
of air.
