A piezometer connected to a water pipeline is primarily used to measure the pipe's:
Correct answer: C. Pressure head
- A. Friction head
- B. Velocity head
- C. Pressure head
- D. Elevation head
Explanation
A piezometer indicates the pressure head at the connection point as a water column. Velocity head is associated with motion, while friction head represents energy loss and elevation head represents level above a datum.

About Hydraulics and Water Resources
Hydraulics studies fluid properties, pressure, buoyancy, continuity, Bernoulli's equation, momentum, pipe flow, open-channel flow and hydraulic machines. Water resources extends these principles to pumps, turbines, reservoirs, irrigation, floods and hydrology, while distinguishing laminar from turbulent flow and uniform from gradually varied channel flow.
