The locus of elevations that water will rise in a series of pitot tubes is called:
Show Hint
The hydraulic grade line is important for understanding the relationship between pressure and elevation in fluid systems. It is crucial for ensuring that the system has enough pressure to overcome pipe friction and reach the desired height.

Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
The hydraulic grade line (HGL) represents the locus of points showing the elevation to which water will rise in a piezometer tube. It includes both the pressure head and the elevation head at each point along the pipe. It gives a visual representation of the pressure at various points in the system, and it is used to analyze and understand flow dynamics in pipes and open channels.
