1. What is Specific Weight of Liquid?

The Specific Weight of Liquid refers to the weight per unit volume of that substance. It is an important property in fluid mechanics that helps determine the behavior of fluids under various conditions.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ \gamma_f = \frac{32 \times \mu \times V_{mean} \times L_p}{h_{location} \times D_{pipe}^2} \]

Where:

\( \gamma_f \) — Specific Weight of Liquid (N/m³)
\( \mu \) — Dynamic Viscosity (Pa·s)
\( V_{mean} \) — Mean Velocity (m/s)
\( L_p \) — Length of Pipe (m)
\( h_{location} \) — Head Loss due to Friction (m)
\( D_{pipe} \) — Diameter of Pipe (m)

Explanation: This formula calculates the specific weight of a liquid based on the head loss due to friction in a pipe system, taking into account the fluid's viscosity, flow velocity, and pipe dimensions.

3. Importance of Specific Weight Calculation

Details: Calculating specific weight is crucial for designing fluid systems, determining pump requirements, analyzing pressure drops, and understanding fluid behavior in various engineering applications.

4. Using the Calculator

Tips: Enter all values in the appropriate units (Pa·s for viscosity, m/s for velocity, and m for length, head loss, and diameter). All values must be positive and non-zero.

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 acceleration due to gravity.

Q2: What are typical specific weight values for common liquids?
A: Water has a specific weight of approximately 9810 N/m³, while other liquids vary based on their density and gravitational acceleration.

Q3: How does temperature affect specific weight?
A: Temperature affects density and viscosity, which in turn affects specific weight. Most liquids decrease in specific weight as temperature increases.

Q4: What is head loss due to friction?
A: Head loss due to friction is the energy loss in a fluid system caused by the fluid's viscosity and the roughness of the pipe walls.

Q5: When is this calculation particularly useful?
A: This calculation is particularly useful in pipe flow analysis, hydraulic system design, and when determining fluid properties in closed conduit systems.
