Calculate the height to which water will rise in capillary tube of 1.5 mm diameter. Surface tension of water is 7.4 xx 10^(-3) Nm^(-1).

Calculate the height to which water will rise in capillary tube of 1.5

1.	Calculate the height to which water will rise in capillary tube of 1.5 mm diameter. Surface tension of water is 7.4 xx 10^(-3) Nm^(-1).
Answer» Solution :Here, `r = (1.5)2 = 0.75 mm = 0.75 XX 10^(-3) m` `sigma = 7.4 xx 10^(-3) Nm^(-1)` For water, `rho = 10^3 m^(-3)` ANGLE of CONTACT`"" theta = 0^@` `h = (2 sigma cos theta)/(r rho G) = (2 xx 7.4 xx 10^(-3) xx cos 0^@)/(0.75 xx 10^(-3) xx 10^3 xx 9.8)` `h = 0.002014 m`
