Explanation: The vertical intercept between EGL and HGL is equal to the kinetic head. For a pipe of uniform cross-section, there will be no change in the velocity of flow across the pipe. Since the kinetic head remian constant, the slope of HGL will be equal than that of EGL.

Explanation:
1. Slope of EGL and HGL:
- The slope of the Energy Grade Line (EGL) represents the energy head loss per unit length along the flow direction in a pipe.
- The slope of the Hydraulic Grade Line (HGL) represents the total head loss per unit length along the flow direction in a pipe.
2. Pipe of Uniform Cross-section:
- In a pipe of uniform cross-section, the EGL and HGL coincide as the total head loss is equal to the energy head loss.
- This means that the slope of the HGL will be equal to the slope of the EGL for a pipe of uniform cross-section.
3. Relationship between EGL and HGL slopes:
- Since the total head loss and energy head loss are the same in a pipe of uniform cross-section, the slopes of the EGL and HGL will be equal.
- This relationship holds true regardless of the flow rate, pipe diameter, or fluid properties in the pipe.
Therefore, the correct answer is option 'C' - equal to that of EGL for a pipe of uniform cross-section.
