NozzlePro datasheets list flow rates at a reference pressure in PSI (typically 40 PSI). Supplier datasheets from European manufacturers commonly use bar or kPa. Before using the Flow Rate Estimator, convert your supply pressure to the same unit as the datasheet reference pressure โ or use the Flow Rate Estimator directly, which accepts mixed units and converts automatically. When comparing nozzles across datasheets using different pressure units, always convert to a common unit first to ensure you are comparing at the same operating condition.
