Q.

An arrangement of the pipes of circular cross-section is shown in the figure. The flow of water (incompressible and nonviscous) through the pipes is steady in nature. Three sections of the pipe are marked in which section 1 and section 2 are at same horizontal level, while being at a greater height than section 3. Radius of section 1 is R1,  radius of section 2 is R2 and radius of section 3 is  R3 such that R2>R1  and  R2=R3. Correctly match order of the different physical parameter with the options given. In column-I certain statements are given and numbers given in column-II represent the section shown in figure. Match the statements in column-I with corresponding ranking in column-II
