Explanation: The vertical intercept between EGL and HGL is equal to the kinetic head. For a nozzle, the cross-sectional area decreases in the direction of flow leading to an increase in the velocity of flow across the pipe. Since the kinetic head increases, the vertical intercept between EGL and HGL will increase.

Explanation:
- EGL (Energy Grade Line) represents the total head of the fluid at any point along the pipe.
- HGL (Hydraulic Grade Line) represents the pressure head of the fluid at any point along the pipe.
- The difference between EGL and HGL is the velocity head of the fluid.
Now, coming to the question,
- When a nozzle is introduced in a pipeline, it causes a sudden contraction in the flow area, resulting in an increase in fluid velocity and hence the velocity head.
- As a result, the EGL rises above the HGL, and the vertical distance between them is equal to the velocity head.
- Therefore, the vertical intercept between EGL and HGL increases with the introduction of a nozzle in a pipeline.
Hence, the correct answer is option 'A' - increases.
