____________ is the determining factor for the number of bubble caps to be used per tray?
Correct answer: A. Permissible slot velocity
- A. Permissible slot velocity
- B. Tray diameter
- C. Liquid load
- D. Vapor load
Explanation
The number of bubble caps is selected using the permissible vapour velocity through the cap slots, together with the available vapour load. The permissible slot velocity is therefore the direct sizing criterion for cap number.
