Question

Water level in piezometer represents:

• A. Water table
• B. Phreatic water level
• C. Pressure head in pipe during pumping
• D. Pressure head in pipe during rainy season

Hint:

Piezometer measures pressure head.
It is used in fluid mechanics and groundwater studies.
The water level rises to the pressure head height.

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
A piezometer is used to measure pressure head.
It is a simple tube that measures water pressure.

Step 2: Key Formula or Approach:
No specific formula.
Need to know the use of a piezometer.

Step 3: Detailed Explanation:
A piezometer measures the pressure head at a specific point.
It is often used in pipes to measure water pressure during pumping.
The water level in the piezometer represents the pressure head.
It does not directly represent the water table or phreatic level.
Thus, it represents the pressure head in a pipe during pumping.

Step 4: Final Answer:
Water level in piezometer represents pressure head in pipe during pumping.
Hence, the correct option is (C).
