About

EdgeSpace Pipe Size Calculator is a professional field calculator for plumbers, pipefitters, HVAC technicians, and construction workers. Enter flow rate and velocity to estimate recommended NPS (Schedule 40 inside diameters). Switch modes to check velocity in an existing pipe or max flow at a target speed. Fully offline. WHAT YOU GET • A = Q ÷ V D = √(4A / π) • Recommended NPS from flow + velocity • Velocity from pipe + flow • Max flow from pipe + velocity • Units: GPM, L/min, L/s, m³/h and ft/s, m/s • Velocity presets 2–8 ft/s • Schedule 40 catalog ½″–8″ with DN • Live pipe diagram • Share, copy, and PDF • Local history and favorites Estimated sizing — actual selection depends on material, schedule, fittings, pressure loss, fluid, and codes.
