The distance between the centers of the two arms of a U-tube open to the atmosphere is 25 cm, and the U-tube contains 20-cm-high alcohol in both arms. Now the U-tube is rotated about the left arm at 4.2 rad/s. Determine the elevation difference between the fluid surfaces in the two arms.
Correct answer is 'Range: 5.6 to 5.7'. Can you explain this answer?
Verified Answer
The distance between the centers of the two arms of a U-tube open to ...
When the U-Tube will rotate
p1 = p2 = patm For forced vortex
p = ρω2r2 / 2 − ρgZ + C
Equating pressures at 1 & 2
ρω2(0)2 /2− ρg(0) = ρω2r2/2 /2 − ρgh
i. e ω2r2/2 / 2 = gh
(4.2)2(0.25)2 /2 = gh
h = 5.61 cm
