(The figure shows the effect of tube radius on the height to which capillary action can raise a fluid. In this problem, assume the contact angle for water and glass is 0°.
d1=1.8 cm
H2= 3.95cm)
1) Calculate the height h, in meters, for water in a glass tube with a diameter of 1.8 cm, a rather large tube like the one on the left. Assume the surface tension of water is 0.0728 N/m.
2) What is the radius, in meters, of the glass tube on the right if it raises water to 3.95 cm?
