Document Summary
Shear stress- the tangential force divided by the area. Stress vector- the force vector divided by the area. Normal stress-the normal component of force divided by the area. Continuum- continuous distribution of a liquid or gas throughout the region of interest. Standard atmospheric conditions- a pressure of 101. 3 kpa and temperature of 15*c. Absolute pressure- the scale measureing pressure where zero is reached when an ideal vacuum is achieved. Gage pressure- the scale measureing pressure relative to the local atmospheric pressure (cid:1868)(cid:3028)(cid:3029)(cid:3046)(cid:3042)(cid:3039)(cid:3048)(cid:3047)(cid:3032)=(cid:1868)(cid:3028)(cid:3047)(cid:3040)(cid:3042)(cid:3046)(cid:3043) (cid:3032)(cid:3045)(cid:3030)+(cid:1868)(cid:3028)(cid:3032) Vacuum- wherever the absolute pressure is less than the atmospheric pressure. Specific gravity- the ratio of the density of a substance to the density of water. Strain rate- the rate at which a fluid element deforms. No-slip condition- condition where viscosity causes fluid to adhere to the surface. Vapor pressure- the pressure resulting from molecules in a gaseous state. Cavitation- bubbles form in a liquid when the local pressure falls below the vapor pressure of the liquid.
