Concept:
Hydraulic gradient line: The summation of the datum head and pressure head of a fluid flowing through a pipe with reference to a certain line is known as hydraulic gradient line (H.G.L).
Energy gradient line: The summation of the pressure head, velocity head, and datum head of a fluid flowing through a pipe with respect to a certain line is known as energy gradient line (E.G.L).
Note:
- The difference between E.G.L and H.G.L gives kinetic head.
- H.G.L lies below the E.G.L.
- For a uniform section pipe, the slope of H.G.L and E.G.L is equal because the velocity across the pipe is not changing, so the kinetic head remains constant.
Thus, option (3) is the correct answer.
