Question

Capillary Rise as a Function of Time and Reservoir Type A capillary tube is brought into contact with a liquid as shown in the Figure 2A. Match the curves of height versus time (Figure 2B) with the corresponding cases 1,2 and 3 described below. Case 1: The water is in a large reservoir. What is the equilibrium height for this case? Case 2: The capillary is placed in contact with a drop of initial diameter 0.3 cm and remains in contact as the liquid is transferred into the capillary Case 3: The capillary is placed in contact with a drop of initial diameter 0.4 cm and remains in contact as the liquid is transferred into the capillary. Explain your conclusion briefly for each case. In all cases the liquid is water and the capillary has an inner diameter of 1 mm and height of 10 cm. Time t=0 is defined as the time at which the lower end of the capillary is first brought in contact with the water. Gravity acts down.

          Capillary Rise as a Function of Time and Reservoir Type
A capillary tube is brought into contact with a liquid as shown in the Figure 2A. Match the curves of
height versus time (Figure 2B) with the corresponding cases 1,2 and 3 described below.
Case 1: The water is in a large reservoir. What is the equilibrium height for this case?
Case 2: The capillary is placed in contact with a drop of initial diameter 0.3 cm and remains in
contact as the liquid is transferred into the capillary
Case 3: The capillary is placed in contact with a drop of initial diameter 0.4 cm and remains in
contact as the liquid is transferred into the capillary.
Explain your conclusion briefly for each case. In all cases the liquid is water and the capillary has an
inner diameter of 1 mm and height of 10 cm. Time t=0 is defined as the time at which the lower end
of the capillary is first brought in contact with the water. Gravity acts down.
