A Rotameter works on the principle of _______________ pressure drop?
Correct answer: A. Constant
- A. Constant
- B. Variable
- C. Both A. & B.
- D. Neither A. nor B.
Explanation
A rotameter operates with a nearly constant pressure drop across its float, while the float position changes until the upward fluid force balances its effective weight. The changing annular flow area then indicates the flow rate.
