1. What is Specific Weight?

Specific Weight (γₛ) is defined as the weight per unit volume of a substance. It represents the force exerted by gravity on a unit volume of a material and is measured in Newtons per cubic meter (N/m³).

2. How Does the Calculator Work?

The calculator uses the specific weight formula:

Where:

• \( \gamma_s \) — Specific Weight (N/m³)
• \( \rho \) — Density of the substance (kg/m³)
• \( g \) — Gravitational acceleration (9.80665 m/s²)

Explanation: The formula multiplies the density of the material by the gravitational acceleration constant to calculate the weight per unit volume.

3. Importance of Specific Weight Calculation

Details: Specific weight is crucial in fluid mechanics, civil engineering, and material science for calculating buoyancy forces, structural loads, and material properties in various applications.

4. Using the Calculator

Tips: Enter the density of the substance in kilograms per cubic meter (kg/m³). The value must be greater than zero for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between density and specific weight?
A: Density is mass per unit volume (kg/m³), while specific weight is weight per unit volume (N/m³). Specific weight includes the effect of gravity.

Q2: Does specific weight change with location?
A: Yes, since gravitational acceleration varies slightly at different locations on Earth, specific weight will also vary accordingly.

Q3: What are typical specific weight values for common materials?
A: Water has specific weight of approximately 9806.65 N/m³, steel about 78500 N/m³, and air about 12.07 N/m³ at standard conditions.

Q4: How is specific weight used in engineering applications?
A: It's used in calculating fluid pressures, buoyancy forces, structural loads from fluids, and in designing hydraulic systems.

Q5: Can this calculator be used for any material?
A: Yes, as long as you know the density of the material, you can calculate its specific weight using this formula.
