Question

Name Fluid Mechanics I (4600:310:301, Summer 2020,6/16, Tuesday) Application of Hydraulic Pressure Variation in Liquids - Measurement of Pressure: 1. Atmospheric pressure, Absolute pressure, and Gage pressure (or vacuum pressure) 1 Gage pressure @ 1 Standard atmospheric pressure: Patm = 760 mm Hg (abs) = 101.3 kPa(abs) = 14.7 (psia) = 1 (bar) Pressure Absolute pressure Local atmospheric pressure reference 2 Gage pressure @ 2 (suction or vacuum) Absolute pressure @ 2 This book employs the gage pressures unless specifically designated absolute. Absolute zero reference
