  2. The rate of gas flow through a humidifier determines contact time.
  3. Low flows decrease and high flows increase relative humidity output.
  4. Bubble humidifier contact time depends on the water column depth.
  a. 1 and 3 only

Answer to Question 1

ANS: D

Answer to Question 2

ANS: B
In passover and wick-type humidifiers, the flow rate of gas through the humidifier is inversely related to contact time, with high flow rates reducing the time available for evaporation to occur.
