In that absence of gravity rise in a capillary tube provided there is no gravity acting on it? |
|
Answer» Solution :In the absence of gravity, these is no resistance against the rise of a liquid in a capillary TUBE to surface tension, So, If the length of the capillary tube is infinite, WATER will rise to that infinite height. Again, if the tube is of finite length, water fill it up completely. Even if water SPILLS out, due to capillary ACTION, more water will be drawn into the tube to fill it completely. Capillary rise, `h=(2Tcostheta)/(r rho g)` In absence of gravity, g = 0. So, `hto oo`. |
