Fittings Water Storage

Overview

Engineering reference data for Fittings Water Storage 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

Symbol	Description	Unit
$\sigma$	Stress	Pa
$\varepsilon$	Strain	—
$E$	Young's modulus	Pa
$\alpha$	Thermal expansion coefficient	1/°C
$\Delta T$	Temperature change	°C

Water Storage Capacity by Fixture

The following table shows 24-hour storage requirements for commonly used cold water fittings.

Water Storage Capacity by Building Type

The following table shows 24-hour storage requirements per person for different building types.

Design Guidelines

For domestic dwellings, the recommended minimum water storage capacity is 200 – 300 liters (53 – 79 gallons). This ensures adequate supply for typical household demand over a 24-hour period.

Note: Actual storage requirements depend on occupancy levels, fixture count, and peak demand patterns. Refer to CIBSE Guide G (2004) Public Health Engineering for detailed sizing methodology.
