where, ρ1 and ρ2 are respective densities, A1 and A2 the cross sectional areas and V1 and V2 are the velocities, respectively. By using value for the mass flow rate in
Table-1, exit velocity of 1.5m/s and substituting A2 in (1), the diameter of the scrubber was determined to be 8.0m. The height of the spray tower system has been determined
to be 16m by considering typical height to diameter ratio of cylindrical shell of approximately 2:1 in Cheremisin off
and Young [15].
