A liquid flow 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

Question:

7.A liquid flow 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) v_{2} - v_{1} = √(2gh)
c) v_{2} ^ 2 - v_{1} ^ 2 = 2gh
d) The energy per unit mass of the liquid is the sections of the tube

Answer :

c) v_{2} ^ 2 – v_{1} ^ 2 = 2gh
