Momentum and CollisionHard
Question
A liquid flows through a horizontal tube. The velocities of the liquid in the two sections, which have areas of cross-section A1 and A2, are v1 and v2 respectively. The difference in the levels of the liquid in the two vertical tubes is h -
Options
A.The volume of the liquid flowing through the tube in unit time is A1v1
B.v2 - v1 = 
C.v22 - v12 = 2gh
D.The energy per unit mass of the liquid is the same in both sections of the tube.
