The operation of a Rotameter is based on ________________?
Correct answer: A. Variable flow area
- A. Variable flow area
- B. Rotation of a turbine
- C. Pressure drop across a nozzle
- D. Pressure at a stagnation point
Explanation
A rotameter uses a float that rises until the flow force balances its weight, while the tapered tube provides a variable flow area. Turbine rotation and nozzle pressure drop describe other flow-measurement principles.
