Ibuprofen belongs to a class of medications called nonsteroidal anti-inflammatory drugs (NSAIDs) that reduce pain and inflammation.
The torr (symbol: Torr) is a non-SI unit of pressure with the ratio of 760 to 1 standard atmosphere, chosen to be roughly equal to the fluid pressure exerted by a millimeter of mercury, i.e., a pressure of 1 Torr is approximately equal to one millimeter of mercury.
Introduction to Pressure in Fluid Mechanics. 1  Pressure always acts inward normal to any surface (even imaginary surfaces as in a control volume). 2  Pressure is a normal stress, and hence has dimensions of force per unit area, or {ML-1T-2}. 3  Standard atmospheric pressure is 101.3 kPa (0.1013 MPa) or 14.69 psi.
