Verified Answer
Consider the following statements relating to hydraulic gradient line ...
Answer : c)2, 3, and 4 are correct
Statement (1): hydraulic gradient line and energy gradient line "never" coincide because hydraulic grade line lies one velocity head below the the energy line. So, statement one is totally "wrong".

Consider the following statements relating to hydraulic gradient line ...
Explanation:
Hydraulic gradient line (HGL) and energy gradient line (EGL) are two important concepts in fluid mechanics. They are used to determine the direction and magnitude of fluid flow in pipelines and channels.

1. In the case of a fluid flowing in a pipeline, hydraulic gradient line and energy gradient line may coincide.

- This statement is true. In some cases, HGL and EGL may coincide, especially when there is no change in the velocity head or when the fluid is in steady-state flow.

2. The line joining the points representing piezometric heads is known as hydraulic gradient.

- This statement is true. The hydraulic gradient is the line that connects the points of equal piezometric head. It represents the slope of the pressure head for a particular fluid flow.

3. In the case of ideal fluid, energy gradient line is always horizontal.

- This statement is false. In the case of an ideal fluid, the EGL is always horizontal, not the HGL. The EGL represents the total energy of the fluid, i.e., the sum of pressure head, velocity head, and elevation head. Since an ideal fluid has no viscosity, there is no loss of energy due to friction, and the EGL remains horizontal.

4. Hydraulic gradient line has a downward slope in the case of flow through pipes.

- This statement is true. The HGL represents the pressure head of the fluid, and it has a downward slope in the direction of flow due to the pressure drop caused by friction losses.

Therefore, the correct option is C, i.e., statements 2, 3, and 4 are correct.
