A vertical knock-out drum is used to remove droplets from a gas-liquid stream by gravitational settling.
Assume droplets larger than 100 um will settle out. (.0001 m)
The droplets are water and the vapor is steam at 100 degrees C and 1 atm. Vapor flow rate is 7.2 kg/h.
The height to diamter ratio is 3:1.
What is the size of the drum?
