Question

9.68. A co-flow wet scrubber has QG = 104 cfm, Q1 = 10 cfm, A = 0.6 ft?, and an inlet liquid velocity of zero. The gas has the same properties as air, and the liquid the same properties as water. (a) Estimate the pressure drop of the scrubber. (b) Estimate the aerodynamic cut diameter. (c) Estimate the physical cut diameter, if the particle density is 2 g/cm and C = 1.3.

Answer 1
