Pulsation Dampener Calculator

Measurement
V= Volume per Stroke in Cubic Inches (in*)
GPH = Volume per Stroke in Cubic Inches (in3) = (GPH/60 / Strokes/Min) x 231
GPM = Volume per Stroke in Cubic Inches (in3) = (GPM / Strokes/Min) × 231
Type of Gas
Y = 0.714 if charged with compressed air
Y = 0.714 if charged with nitrogen

GPH or GPM will appear conditionally based on selection above
