What is fluid? 2 PHYS 2101, P.M.Shikhaliev LSU, Fall 2010 Fluid – is a substance that can flow Fluids – liquids, gases 14.3. Density and pressure 3 PHYS 2101, P.M.Shikhaliev LSU, Fall 2010 – density of non-uniform fluid – density of uniform fluid – pressure when applied force is not uniform – pressure when applied force is uniform Units of pressure: 1 atm = 0.98 bar = 1.01 x 10 5 Pa = 760 mm Hg = 760 Torr = 14.7 lb/in 2 = 1 kg/cm 2 1 Pa = 1N/m 2 Hg = 13.6 g/cm 3 14.4.
