MECHANICAL PROPERTIES OF FLUIDS

Two narrow bores of diameters 3.0 mm and 6.0 mm are joined together to form

a U-tube open at both ends. If the U-tube contains water, what is the difference in its levels in the two limbs of the tube ? Surface tension of water at the temperature of the experiment is 7.3 × 10–²N m–¹. Take the angle of contact to be zero and density of water to be 1.0 × 10³ kg m–³ (g = 9.8 m s–²) .
