Two capillary tubes of different diameters are dipped in water. The rise of water is
the same in both tubes
greater in the tube of larger diameter
greater in the tube of smaller diameter
independent of the diameter of the tube
Spheres of iron and lead having same mass are completely immersed in water. Density of lead is more than that of iron. Apparent loss of weight is w1 for iron sphere and w2 for lead sphere, Then is
> 1
= 1
become 0 and 1
= 0
Two solds P and Q float in water. It is observed that P floats with half of its volume immersed and Q floats with rd of its volume is immersed. The ratio of densities of P and Q is
A flow of liquid is streamline, if the Reynold's number is
less than 1000
greater than 1000
between 2000 to 3000
between 4000 to 5000
An ideal fluid flows through a pipe of circular cross-section with diameters 5 cm and 10 cm as shown in the figure. The ratio of velocities of fluid at A and B is
4 : 1
1 : 4
2 : 1
1 : 2
