Darcys law - Study guides, Class notes & Summaries

groundwater velocity ~ cm/yr to 250m/day driven by elevation and water pressure darcys law ~ v=Ki greater difference in hydraulic head or height of water table over distance = faster flow hydraulic head: elevation of measuring point plus the height of water above, h=z(elevation)+w(weight of water table) hydraulic gradient: slope of water table, i=dh/dd artesian ~ any groundwater under pressure that rises above the level of the aquifer wells ~ must penetrate below water table p...

ASBOG Hydrogeology Questions And Answers Area of Influence - ANS-The area within the potentiometic surface is lowered by withdrawal or raised by injection, of water through well. Aquifer - ANS-A geologic unit that is saturated and sufficiently permeable to transmit significant economic quantities of water to wells and springs Capillary Fringe - ANS-The lowest part of the zone of aeration, immediately above the water table, where water is under pressure that is less than atmospheric pre...

What is a fold line and how is it used? - ANSWER-The fold line is a hinge line along which a vertical cross section may be constructed and then flattened out to a horizontal or map view. It is used to represent the subsurface along any given line in a map view. It need not be perpendicular to strike. What is the angle and side relationships for the sin equation? - ANSWER-sinα = opposite side/hypotenuse What is the angle and side relationships for the tanget equation? - ANSWER-tanα = oppo...

What does the "Single-Point Resistivity Log" show and what area is it limited to? - ANSWER-A log that measures the resistivity using 2 electrodes and having a limited area of investigation of from 5 to 10 times the electrode diameter What is the "Area of Influence" of a well? - ANSWER-The area within which the potentiometric surface is lowered by withdrawal or raised by injection, of water through a well Define aquifer - ANSWER-A geologic unit that is saturated and sufficiently permeab...

The essay elucidates how substances are transported over extended distances within animals, addressing the limitation of diffusion over longer ranges. It dissects the requisite mechanisms: a pump generating pressure gradients, bulk flow systems to carry substances, and uptake systems for their retrieval. Detailing pumps like the heart, respiratory mechanisms, and peristalsis in the digestive system, it highlights their roles in creating pressure differentials. Diving into Darcy’s Law, it explo...
