A long capillary tube with both ends open is filled with water and set in a vertical position. What will be the height of column of water remaining in the tube? The radius of the tube is 1mm and surface tension of water is 0.07 newton/meter.

The capillary rise in a tube of diameter 1mm when surface tension of water is 0.06 Nm^-1 is

In a capillary tube of diameter 10^-3m , water rises to a height of 0.03 m. calculate the surface tension of water.

What should be the maximum average velocity of water in a tube of diameter 25mm so that the flow is laminar?

Water rises in a capillary tube to a height 2cm. In another capillary tube whose radius is one third of it, how much the water will rise? If the first capillary tube is inclined at an angle 60^0 with the vertical, then what will be the position of water in the tube?

The cylindrical tube open at both ends has fundamental frequency f in air.The tube is dipped vertically in water so that half of it is in water.The fundamental frequency of the air coloumn is now

Mercury has an angle of contact equal to 140^@ with soda lime glass. A narrow tube of radius 1.00 mm made of this glass is dipped in a trough containing mefcury. By what amount does the mercury dip down in the tube relative to the liquid surface outside? Surface tension of mercury at the temperature of the experiment is 0.465 N m^-1 . Density of mercury = 13.6 xx 10^3 kg m^-3

In an experiment to determine the surface tension of water by capillary rise, water rises to a height of 0.03m in a capillary tube of diameter 10^-3 m. If the angle of contact is negligibly small, calculate the surface tension of water.

A narrow tube of radius 1.0 mm made of glass is dipped in mercury. By what amont does the mercury dip down in the tube relative to the mercury surface outside?

The length of a cylindrical glass tube is 30 cm.the velocity of sound in air is 330 m(s)^-1 .What is the fundamental frequency of vibration of the air coloumn if (i)both ends of the tube are open and (ii)open end is closed and flat?

A vessel is in the form of an inverted cone.Its height is 8 cm and the radius of its top,which is open,is 5 cm.It is filled with water up to the brim.When lead shots,each of which is a sphere of radius 0.5 cm are dropped into the vessel,one-fourth of the water floes out.Find the number of lead shots dropped in the vessel.
