Float Glass Weight

Overview

Engineering reference data for Float Glass Weight in material science and properties.

Key Formulas

Stress

$\sigma = \frac{F}{A}$

Force per unit area.

Strain

$\varepsilon = \frac{\Delta L}{L_0}$

Change in length per original length.

Hooke's Law

$\sigma = E \varepsilon$

Stress proportional to strain in elastic region.

Thermal Expansion

$\Delta L = \alpha L_0 \Delta T$

Length change due to temperature.

Variables

Glass Weight Data

The following table shows the standard weight per square meter for common float glass thicknesses.

Weight Calculation

The weight of float glass is directly proportional to its thickness. The constant of proportionality is derived from the standard density of glass ($\rho \approx 2500 \, \text{kg/m}^3$).

The formula for calculating the weight per unit area is:

$$W = \rho \cdot t$$

Where:

• $W$ is the weight per unit area (kg/m²).
• $\rho$ is the density of glass ($\text{kg/m}^3$).
• $t$ is the glass thickness (m).

For practical use with thickness in millimeters (mm), the formula simplifies to:

$$W = 2.5 \cdot t$$

This simplification accounts for the density and the unit conversion ($1 \, \text{m} = 1000 \, \text{mm}$), explaining the consistent 2.5 kg/m² increase per millimeter of thickness observed in the data table.
