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

c)as speed changes, wavelength and frequency change.

everything changes!
