Document Summary

Density ( ): the mass m per volume v; = m/v; units: kg/m3. The denser a material, the more mass it has in any given volume; the density of a substance is the same regardless of the total amount we have in a system of water is 1000 kg/m3; Pressure: the amount of force, f, per area a; p= f/a; units: n/m2. P is increased if the force applied to a given area is increased, or if a given force is applied to a smaller area. Atmospheric pressure: pressure that is the direct result of the weight of the air above us; pat= 1. 01*105 n/m2; 101 kpa; 14. 7 lb/in2. The pressure in a fluid acts equally in all directions, and acts at right angles to any surface. Gauge pressure (pg)= p- pat; for example, if a tire is to be inflated to a gauge pressure of 241, it must be inflated to that amount plus the amount of atmospheric pressure.
