A liquid flows through a horizontal tube. The velocities of the liquid

1.	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 upsilon_(1)andupsilon_(2) respectively. The difference in the levels of the liquid in the two vertical tubes is h. a) The volume of the liquid flowing through the tube in unit time is A_(1)upsilon_(1). b) upsilon_(2)-upsilon_(1)=sqrt(2gh) c) upsilon_(2)^(2)-upsilon_(1)^(2)=2gh d) The energy per unit mass of the liquid is the same in both sections of the tube.
