1. What is Height of Liquid in Piezometer?

The height of liquid in a piezometer is defined as the maximum height of liquid in a capillary tube, which is inversely proportional to the tube's diameter. It represents the pressure head corresponding to the water pressure at that point.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Hl \) — Height of Liquid (meters)
• \( pw \) — Water Pressure (Pascal)
• \( \rho w \) — Water Density (kg/m³)
• \( g \) — Acceleration Due to Gravity (m/s²)

Explanation: The formula calculates the height of liquid column that would produce the given water pressure, based on the density of water and gravitational acceleration.

3. Importance of Height Calculation

Details: Calculating the height of liquid in a piezometer is crucial for pressure measurement in fluid mechanics, hydrology, and various engineering applications where liquid column height represents pressure head.

4. Using the Calculator

Tips: Enter water pressure in Pascal, water density in kg/m³, and acceleration due to gravity in m/s². All values must be positive numbers greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What is a piezometer used for?
A: A piezometer is used to measure liquid pressure in a system by measuring the height to which liquid rises in a tube.

Q2: Why does tube diameter affect liquid height?
A: In capillary tubes, smaller diameters create greater capillary action, which can affect the maximum height the liquid can reach.

Q3: What is the standard value for water density?
A: The standard density of water is 1000 kg/m³ at 4°C, but it varies slightly with temperature.

Q4: What is the standard value for gravitational acceleration?
A: The standard gravitational acceleration is 9.8 m/s², though it varies slightly with location and altitude.

Q5: Can this formula be used for other liquids?
A: Yes, but you must use the appropriate density value for the specific liquid being measured.
