Plumbing
Pipe Expansion Joint Calculator
Calculates how much a pipe will elongate or contract due to a temperature change, accounting for the thermal expansion coefficient of steel, copper, or aluminum. Essential for sizing expansion joints and loops in piping systems.

Plumbing
Water Pressure Loss Calculator
Calculates friction-induced pressure drop along a water pipe using the Hazen-Williams equation. Use it when designing irrigation systems, fire suppression lines, or building water supply networks where adequate pressure at the endpoint matters.
