Question

Two circular tubes are inserted vertically into a large container filled with liquid that has a surface tension of s = 0.07 N/m, and contact angle of q =10 deg. The density of the liquid is 960 kg/m3 the diameter of the first tube is 1.5 mm, and the diameter of the second tube is 2.5 mm. a) calculate how high will the liquid columns rise in each tube. b) Is this in conflict with Pascal’s law?

a  b

Yes it is in conflict with Pascal’s law

Explanation:

From the question we are told that

The surface tension is The contact angle is The density is The first tube diameter is The second tube diameter is The first tube radius is The first tube radius is Generally capillary rise is mathematically represented as For first tube  For second tube  From the values obtained we see that Which means that Pascal’s law has been violated
