Both calculators run independently β change the inputs on either side to compare results.
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.

Plumbing
Water Meter Sizing Calculator
Determines the appropriate water meter size (in inches) for a property by comparing peak flow demand against the meter's rated capacity at the available line pressure. Use it during new construction or meter upgrade planning.
