Key Formulas

Unit Conversion

$y = x \cdot k$

Multiply by conversion factor.

Linear Interpolation

$y = y_1 + \frac{(x - x_1)(y_2 - y_1)}{x_2 - x_1}$

Estimate between two known points.

Percentage

$p = \frac{\text{part}}{\text{whole}} \times 100\%$

Part as fraction of whole.

Variables

Recommended Air Carrying Velocities

The following table provides recommended air carrying velocities for various materials in pneumatic solid transport systems.

Application Notes

The values in the table are guidelines. The optimal air velocity depends on specific material properties (particle size, shape, moisture, bulk density) and system design (pipe diameter, layout, bend radius). Velocities must be high enough to prevent settling and blockages but low enough to minimize wear, pressure drop, and material degradation.

Unit Conversions

• Density: $1 \text{ lb/ft}^3 = 16.018 \text{ kg/m}^3$
• Pressure: $1 \text{ in H}_2\text{O} = 248.8 \text{ N/m}^2 (\text{Pa}) = 0.0361 \text{ lb/in}^2 (\text{psi}) = 25.4 \text{ kg/m}^2$
