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

Options

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.

Answer

A, C, D
