Choking in case of pipe flow means that a___________________?
Correct answer: A. Specified mass flow rate cannot be achieved
- A. Specified mass flow rate cannot be achieved
- B. Valve is closed in the line
- C. Restriction in flow cross-section area occurs
- D. None of these
Explanation
Choking occurs when the flow reaches its limiting, usually sonic, condition and increasing the driving pressure cannot produce the specified mass flow. It is not simply the closing of a valve or any ordinary restriction.
