Water in a closed tube (see fig) is heated with one arm vertically placed above a lamp. Water will begin to circulate along the tube in counter-clockwise direction.

Water rises to a height h in a capillary tube lowered vertically into water to a depth l as shown in the figure. The lower end of the tube is now closed, the tube is the taken out of the water and opened again. The length of the water column remaining in the tube will be .

An empty barometric tube 1 m long is lowered vertically (mouth downwards) into a tank of water. What will be the depth above the water level in the tube, when the water has risen 20 cm inside the tube ? Take atmospheric pressure as 10.4 m column of water.

A glass tube of circular cross section is closed at one end. This end is weighted and the tube floats vertically in water, heavy end down. How far below the water surface is the end of the tube? Given: outer radius of the tube is 0.14 cm , mass of weighted tube is 0.2 g , surface tension of water 73 dyn//cm and g = 980 cms^(-12) .
