What does differential pressure or delta P (ΔP) mean when logging RO data?
What is delta P (ΔP) and what does it mean when logging RO data? The differential pressure (dP) is the pressure lost due to friction as water passes through the system. You take a reading before the pressure vessels and after the pressure ...
