In the following fig. is shown the flow of liquid through a horizontal pipe. Three tubes A, B and C are connected to the pipe. The radii of the tubes A, B and C at the junction are respectively 2 cm, 1 cm and 2 cm. It can be said that the

Options:

A . Height of the liquid in the tube A is maximum

B . Height of the liquid in the tubes A and B is the same

C . Height of the liquid in all the three tubes is the same

D . Height of the liquid in the tubes A and C is the same

Answer: Option D
:
D

As cross-section areas of both the tubes A and C are same and tube is horizontal. Hence according to equation of continuity $v_{A} = v_{C}$ and therefore according to Bernoulli's theorem $P_{A} = P_{C}$ i.e. height of liquid is same in both the tubes A and C.
