1. What is Specific Weight of Liquid in Piezometer?

Specific Weight of Liquid in Piezometer is the ratio of a body's weight P to its volume V. It represents the weight per unit volume of a liquid and is a fundamental property in fluid mechanics and hydrostatics.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( S \) — Specific Weight of Liquid in Piezometer (N/m³)
• \( p \) — Pressure (Pascal)
• \( h \) — Pressure Head (Meter)

Explanation: The specific weight is calculated by dividing the pressure by the pressure head, which gives the weight per unit volume of the liquid.

3. Importance of Specific Weight Calculation

Details: Calculating specific weight is crucial for understanding fluid behavior in various engineering applications, including hydraulic systems, buoyancy calculations, and fluid statics problems.

4. Using the Calculator

Tips: Enter pressure in Pascal and pressure head in meters. Both values must be positive numbers greater than zero for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: What is the difference between specific weight and density?
A: Specific weight is weight per unit volume (N/m³), while density is mass per unit volume (kg/m³). They are related by the equation: specific weight = density × gravity.

Q2: What are typical values for specific weight?
A: For water at 4°C, specific weight is approximately 9800 N/m³. The value varies with temperature and the type of liquid.

Q3: How is pressure head measured?
A: Pressure head is typically measured as the vertical height of a liquid column that produces a specific pressure at its base.

Q4: Can this formula be used for all liquids?
A: Yes, the formula applies to all liquids, but the specific weight value will vary depending on the liquid's properties.

Q5: What are the units of specific weight?
A: Specific weight is measured in Newton per cubic meter (N/m³) in the SI system.
