WebThe hydraulic gradient is the driving force that causes groundwater to move in the direction of maximum decreasing total head. It is generally expressed in consistent units, such as feet per foot. For example, if the difference in water level in two wells 1000 feet apart is 2 feet, the gradient is 2/1000 or 0.002 ( Fig. 3-12 ). http://mdedge.ma1.medscape.com/cardiology/article/197100/interventional-cardiology-surgery/low-flow-low-gradient-aortic-stenosis crystal ball kentucky

WebThe flows can be classified as either forced flow resulting from the gradient of the pressure or the potential of the body force or induced flow resulting from motion of one of the bounding surfaces. Some flow fields that result in 1-D flow are listed below and illustrated in the following figure (Churchill, 1988) WebA) An open-channel flow for which the water-surface slope is less than the slope of the channel bottom. B) An open-channel flow for which the water-surface slope is greater than the slope of the channel bottom. 14 The key to the answer lies in flow resistance, which was addressed at length in Chapter 4.
