Copper Tubes Dimensions Pressure

Overview

Engineering reference data for Copper Tubes Dimensions Pressure in piping systems.

Key Formulas

Continuity

$A_1 v_1 = A_2 v_2$

Mass conservation in pipe flow.

Pressure Drop

$\Delta P = f \frac{L}{D} \frac{\rho v^2}{2}$

Darcy-Weisbach equation.

Pipe Area

$A = \frac{\pi D^2}{4}$

Cross-sectional area of a pipe.

Variables

Data Tables

Material Properties

The pressure ratings in the table are derived from the following yield strengths ($S$) for the base material:

• Annealed Copper Tube: Yield Strength $S = 5100 \text{ psi}$ $(35 \text{ MPa})$
• Drawn Copper Tube: Yield Strength $S = 10000 \text{ psi}$ $(69 \text{ MPa})$

Unit Conversions

Key pressure and dimensional conversions for reference:

• $1 \text{ in} = 25.4 \text{ mm}$
• $1 \text{ MPa} = 1 \text{ N/mm}^2 = 10 \text{ bar} = 145.0 \text{ psi}$
• $1 \text{ psi} = 6.895 \text{ kPa}$

Relevant Standards

• ASTM B88: Seamless Copper Water Tubes (covers Types K, L, M)
• BS 2871: Copper Tubes (covers specifications like Table X, Y, Z)
