Week 2 eesc07 ground water sept, 14, 2016. No flo(cid:449), if there is (cid:374)o gradie(cid:374)t, does(cid:374)"t (cid:373)atter ho(cid:449) per(cid:373)ea(cid:271)le it is. The higher the gradient, the more pressure. The dista(cid:374)(cid:272)e to (cid:449)hi(cid:272)h (cid:449)ater le(cid:448)el rises, it"s a (cid:373)easure of head. A physical quantity capable of measurement at every point in a flow system: ex. Temp, voltage: defined by hubbert in 1940. All driven by diff systems of potential. No difference in current, = no potential: ex. The amt of mechanical e per unit mass of fluid. However, can realte this to properties of elevation, pressure & head (tht can actually be. If know fluid potential difference, then can find out potential measured) Approach this prob by breaking it into 3 e component. Basic equation of fluid mechanics apply to all fluids. Eqn simplies as v 0, thus 2nd term disappears. Water has slight compressibility, can ignore it since compressibility very small.
