EESC07H3 Lecture Notes - Pressure Measurement, Bernoulli'S Principle, Hydraulic Head
Document Summary
Specific discharge (v) (v) = q / a. = apparent velocity: does not represent a true velocity. True velocity will be determined by the open area and not the total cross-sectional area. Only small proportion of a is open area, the actual flow velocity is greater than v. Actual flow velocity = average linear flow velocity or seepage velocity. Some of the pore space is not hydraulically interconnected it"s not contributing to the ground. Vv (volume of voids) refers only to interconnected pore space. Ranges in values of porosity: sedimentary, sedimentary rocks, crystalline rocks. Fracture flow: as ne approaches 0, q value also gets really small. Hydraulic conductivity: hydraulic head and the concept of fluid potential. Voltage: what is potential (as defined by hubbert) a physical quantity capable of measurement at every point in a flow system ; e. g. temperature. Fluid potential , aka force potential is the amount of mechanical energy per unit mass of fluid.
