6. CA = concentration of A, [mol/L]
Henry's Law states that the amount of a gas that dissolves into a liquid is proportional to the partial pressure that gas exerts on the surface of the liquid.
where,
CA = concentration of A, [mol/L]
KH = equilibrium constant (Henry's Law constant), [mol/L-atm]
pA = partial pressure of A, [atm]

23. Design of Electrostatic Precipitators
The efficiency of removal of particles by an Electrostatic Precipitator is given by
η = fractional collection efficiency
w = electrokinetic velocity (drift velocity), m/s.
A = available collection area, m2
Q = volumetric flow rate m3/s s
