Which of the following relationship is valid for the equilibrium position of the float in a Rotameter? (Where, Df= Drag force on the float Bf = Buoyant force on the float Wf = Weight of the float)?
Correct answer: A. Df + Bf = Wf
- A. Df + Bf = Wf
- B. Df = Bf + Wf
- C. Df + Bf + Wf =0
- D. None of these
Explanation
At the rotameter float's equilibrium position, the upward drag and buoyant forces balance its downward weight, giving Df + Bf = Wf.
