💨 Napier Formula (Failed-Open Trap Blow-Through Steam Loss Lbs/hr & $/Yr)

Steam Trap Orifice Leakage Calculator

Calculate thermodynamic steam losses and fuel waste from failed-open thermodynamic, inverted bucket, and thermostatic steam traps using Napier's modified orifice discharge equation: calculate blow-through steam loss (Lbs/hr steam escaping across 15 to 250 PSI steam headers), calculate annual dollar loss, and ultrasonic trap survey audit profits.

1. Project & Operating Inputs

Failed-Open Steam Traps Identified (Trap Count e.g. 14 Failed Traps)

Operating Steam Pressure (PSIG e.g. 125 PSIG Steam Header)

Turnkey Ultrasonic Trap Survey & Replacement CapEx ($ e.g. $18,500)

Cost of Generated Steam ($ / 1,000 Lbs Steam e.g. $14.50 / kLb)
