Solute
is absorbed from a gas into water in a packed bed operating at steady state. The absorber operating pressure and temperature are 1 atm and 300 K, respectively. At the gas-liquid interface
where
and
are the interfacial gas and liquid mole fractions of
, respectively. At a particular location in the absorber, the mole fractions of
in the bulk gas and in the bulk water are 0.02 and 0.002, respectively. If the ratio of the local individual mass transfer coefficients for the transport of
on the gas-side (
) to that on the water-side (
),
, then
equals ____ (rounded off to 3 decimal places).Log in to check the answer
