Document Summary

Fluid: liquid or gas, fluid statics: study of fluids at rest in equilibrium. 12. 1 density: density ( ) = mass / volume o. Unit: kg / m^3: specific gravity: ratio of material"s density to the density of water (1000 kg/m^3) o. 72 kg m(water) = (water)v = (1000 kg/m^3)(60 m^3) = w(water) = m(water)g = (6. 0 x 10. 4 kg)(9. 8 m/s^2) = 5. 9 x 10^5 n = 1. 3 x 10^5 lb = 66 tons. 12. 2 pressure in a fluid: pressure (p) = df(perp) / da o o o o o. If pressure is the same at all points of a finite plane then p = f(perp) / a. F(perp) = net normal force on one side of surface. 1 millibar = 100 pa: atmospheric pressure (pa): pressure of earth"s atmosphere at the surface o. 1 atmosphere (atm) = 101,325 pa = 1. 013 x 10^5 pa.
