A liquid flows through a horizontal tube...

A liquid flows through a horizontal tube. The velocities of the liquid in the two sections, which have areas of cross section `A_(1)` and `A_(2)` are `v_(1)` and `v_(2)` respectively. The difference in the levels of the liquid in the two vertical tubes is `h`. Then

A

The volume of the liquid flowing through the tube in unit time is `A_(1)v_(1)`

B

`v_(2) - v_(1) = sqrt(2gh)`

C

`v_(2)^(2) - v_(1)^(2) = 2gh`

D

The energy per unit mass of the liquid is the same in both sections of the tube
