(Le/D) for fully open gate valves would be __________________?
Correct answer: D. Both B. and C.
- A. Much more than that for fully open globe valves
- B. Much less (say 2% than that for fully open globe valves)
- C. Around 7
- D. Both B. and C.
Explanation
A fully open gate valve offers very little flow resistance, with an equivalent length-to-diameter ratio of roughly 7, far below that of a globe valve. This is approximately 2% of the globe-valve value, so both statements B and C are valid.
