Find the capillarity rise or fall if a capillary tube of diameter .03m is immersed in hypothetical fluid with specific gravity 6.5, surface tension 0.25 N/m and angle of contact 147°.
(a) 0.44mm fall
(b) 0.88mm fall
(c) 0.44mm rise
(d) 0.88mm rise
I had been asked this question during an online exam.
