Water Pressure and Pressure Forces - Pearson
www.pearsonhighered.comThis pressure, , is commonly referred to as the absolute pressure. Pressure gauges are usually designed to measure pressures above or below the atmospheric pressure. Pressure so measured, using atmospheric pressure as a base, is called gauge pressure, P. Absolute pressure is always equal to gauge pressure plus atmospheric pressure: (2.3)
