A 2″ gate valve fitted in a pipe is replaced by a similar globe valve. Pressure drop in gate valve was Δp. For the same discharge, the pressure drop across globe valve is__________________?
Correct answer: B. > Δp
- A. Δp
- B. > Δp
- C. < Δp
- D. Δp2
Explanation
A globe valve has a more tortuous flow path and causes much greater irreversible loss than a streamlined gate valve. At the same discharge, its pressure drop is therefore greater than Δp.
