Properties of Flow net: Flow nets must satisfy the boundary conditions of flow field. Quantity of water flowing through each flow channel is the same. The potential drop in any two consecutive equal potential lines is same/constant. Flow lines and equal potential lines are smooth curves..
People also ask, what is Flow Net and its uses?
A flownet is a graphical representation of two-dimensional steady-state groundwater flow through aquifers. Construction of a flownet is often used for solving groundwater flow problems where the geometry makes analytical solutions impractical. Flow net technique is a graphical representation method.
Furthermore, what are flow lines and equipotential lines? Flow Line: A line along which a water particle moves through a permeable soil medium. (a.k.a. streamline). Equipotential Lines: A line along which the potential head at all points is equal. NOTE: Flow Lines and Equipotential Lines must meet at right angles!
Consequently, what is Flow Net in geotechnical engineering?
A Flow net is a graphical representation of flow of water through a soil mass. It is a curvilinear net formed by the combination of flow lines and equipotential lines. Flow lines represent the path of flow along which the water will seep through the soil.
What is Flow Net diagram?
A flownet is a graphical representation of two-dimensional steady-state groundwater flow through aquifers. As such, a grid obtained by drawing a series of equipotential lines is called a flownet. The flownet is an important tool in analysing two-dimensional irrotational flow problems.

In hydrology, seepage flow refers to the flow of a fluid (water) in permeable soil layers such as sand. The fluid fills the pores in the unsaturated bottom layer and moves into the deeper layers as a result of the effect of gravity. The soil has to be permeable so that the seepage water is not stored.What is quick sand condition?
Quick sand condition or boiling Quick sand condition is a condition of flow, not a type of soil, in which a vertical upward seepage flow causes floating condition of a particle in cohesion less soil such as Sand and fine gravel . ? There is also a pressure in downward direction due to submerged weight of soil.What are equipotential lines?
Equipotential lines are like contour lines on a map which trace lines of equal altitude. In this case the "altitude" is electric potential or voltage. Equipotential lines are always perpendicular to the electric field. In three dimensions, the lines form equipotential surfaces.What is equipotential drop?
The space between two adjacent equipotential lines represents a drop in head. The space between two adjacent equipotential lines is called an equipotential space. FLOW NETS – Equipotential Lines. 6 An equipotential line means potential head at all points is equal (i.e. total head is constant).What is exit gradient?
The maximum value of hydraulic gradient which results in maximum seepage. velocity occurs across smallest square (flow grid). Exit Gradient: The exit gradient is the hydraulic gradient at the downstream end of the. flow line where percolating water leaves the soil mass and emerges into the free water at.What is equipotential line in soil mechanics?
The equipotential line in a seepage through a soil mass is defined as the line connecting the points of equal head of water. The direction of seepage is always perpendicular to the euipotential lines. The flow lines and equipotential line are intersecting lines at 90 degree to each other.What is critical hydraulic gradient?
Critical hydraulic gradient is defined by the hydraulic gradient where particles start to outflow from soil samples. The determination of the critical hydraulic gradient of internal erosion is based on the occurrence of “sand boil” or other indicating phenomena of seepage failure.What is seepage pressure?
Seepage pressure the pressure exerted by water on soil through which it percolates is known as seepage pressure (Ps) it is given by: Ps=h∗ηw.What is meant by hydraulic gradient?
Definition of hydraulic gradient. : a line joining the points of highest elevation of water in a series of vertical open pipes rising from a pipeline in which water flows under pressure.What is phreatic line in earth dam?
The top flow line of a saturated soil mass below which seepage takes place, is called the Phreatic line. This line separates a saturated soil mass from an unsaturated soil mass. It is not an equipotential line, but a flow line. For an earthen dam, the phreatic line approximately assumes the shape of a parabola.What is equipotential line in fluid mechanics?
Equipotential Line is an imaginary line in a field of flow such that the total head is the same for all points on the line, and therefore the direction of flow is perpendicular to the line at all points.
