Understanding Plumbing & HVAC Calculations

Flow Rate Basics

Flow rate is crucial in plumbing and HVAC systems. It determines the volume of fluid passing through a pipe per unit of time, typically measured in gallons per minute (GPM).

Pipe Sizing Guidelines

Proper pipe sizing ensures optimal flow rates and prevents issues like water hammer and excessive pressure drop. Consider both flow velocity and pressure requirements.

Common Applications

These calculations are essential for designing domestic water systems, HVAC hydronic systems, and industrial process piping. They help ensure efficient and reliable operation.
