1. What is the Specific Weight of Liquid Formula?

The Specific Weight of Liquid formula calculates the weight per unit volume of a liquid in a pipe system using Venturi meter measurements. It relates the manometer fluid's specific weight to the Venturi head and meter length.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ \gamma_f = \frac{\gamma_m}{\left(\frac{h_{venturi}}{L} + 1\right)} \]

Where:

\( \gamma_f \) — Specific Weight of Liquid (N/m³)
\( \gamma_m \) — Weight per unit Volume of Manometer Fluid (N/m³)
\( h_{venturi} \) — Venturi Head (m)
\( L \) — Length of Venturi meter (m)

Explanation: This formula calculates the specific weight of the liquid flowing through the pipe based on the pressure difference measured by the Venturi meter and the properties of the manometer fluid.

3. Importance of Specific Weight Calculation

Details: Calculating the specific weight of liquid is essential for fluid dynamics analysis, pipe system design, flow measurement accuracy, and understanding fluid behavior in various engineering applications.

4. Using the Calculator

Tips: Enter the weight per unit volume of manometer fluid in N/m³, Venturi head in meters, and Venturi meter length in meters. All values must be positive and valid.

5. Frequently Asked Questions (FAQ)

Q1: What is specific weight?
A: Specific weight refers to the weight per unit volume of a substance, typically measured in N/m³ in the SI system.

Q2: How does a Venturi meter work?
A: A Venturi meter measures fluid flow by creating a pressure difference between the inlet and the constricted throat section, which can be used to calculate flow rate and fluid properties.

Q3: What are typical values for specific weight?
A: Water has a specific weight of approximately 9810 N/m³ at standard conditions. Other liquids vary based on their density.

Q4: Why is the manometer fluid important?
A: The manometer fluid's specific weight serves as a reference for measuring the pressure difference in the Venturi meter system.

Q5: Can this formula be used for gases?
A: While the principle is similar, gas calculations typically require additional considerations for compressibility and may use different equations.
