Calculate the height to which water will...

Calculate the height to which water will rise in a capillary tube of diameter `1xx10^(-3)`m [given surface tension of water is `0.072Nm^(-1)` angle of contact is `0^(@),g=9.8ms^(-2)` and density of water `=1000kgm^(-3)`]

Text Solution

AI Generated Solution

To calculate the height to which water will rise in a capillary tube, we can use the formula for capillary rise: \[ h = \frac{2T \cos \theta}{\rho g r} \] Where: - \( h \) = height of capillary rise - \( T \) = surface tension of the liquid (water in this case) - \( \theta \) = angle of contact (given as \( 0^\circ \)) ...
