A cylindrical vessel of radius 3 cm has at the bottom a horizontal capillary tube of length 20 cm and internal radius `0.4` mm. If the vessel is filled with water, find the time taken by it to empty one half of its contents. Given that the viscosity of water is `0.01` poise.

A cylindrical vessel of radius 3 cm has at the bottom a horizontal capallary tube of length 20 cm and intrnal radius 0.4 mm. If the vessel is filled with water, find the time taken by it to empty one half of its contents. Given that the viscosity of water is 0.01 poise.

A vessel of cross-section 20xx10^(-4) square metres has a capillary tube of length 10 cm and internal radius 0.5 mm at the bottom. It is initially filled with water to a height of 20 cm above the capillary tube. Find the time taken by the vessel to expt one-half of its contents, given that the viscosity of water of 0.001 SI units. Density of water = 1000 kg per cubic metre. [Hint : See example 5]
