What is an equipotential line or source?
Equipotential lines are like contour lines on a map which trace lines of equal altitude. In three dimensions, the lines form equipotential surfaces. Movement along an equipotential surface requires no work because such movement is always perpendicular to the electric field.
What is the significance of equipotential lines?
Equipotential lines. Equipotential lines provide a quantitative way of viewing the electric potential in two dimensions. Every point on a given line is at the same potential. Such maps can be thought as topographic maps.
How do equipotential lines work?
Equipotential lines are perpendicular to electric field lines in every case. One of the rules for static electric fields and conductors is that the electric field must be perpendicular to the surface of any conductor. This implies that a conductor is an equipotential surface in static situations.
What is streamline and equipotential line?
Streamline: It is an imaginary curve drawn in space such that tangent drawn to it at any point will give the velocity of that fluid particle at a given instant of time. Equipotential line: A line along which velocity potential function (ϕ) is constant is known as the equipotential line.
What is equipotential line in geotechnical engineering?
The points along the equipotential line will have the equal head, which causes the flow. If we place the piezometer at different points along an equipotential line, the water level will be same. This is the line present in the flow net, and also called as drop line.
How is equipotential calculated?
Equipotential lines are perpendicular to electric field lines in every case. W = −ΔPE = −qΔV = 0. W = Fd cos θ = qEd cos θ = 0. Note that in the above equation, E and F symbolize the magnitudes of the electric field strength and force, respectively.
What is equipotential function?
Equipotential or isopotential in mathematics and physics refers to a region in space where every point in it is at the same potential. An equipotential of a scalar potential function in n-dimensional space is typically an (n−1)dimensional space.
What is the slope of equipotential line?
We will conclude here that the product of slope of equipotential line and slope of stream line at the point of interseaction will be equivalent to -1. Therefore we can say that equipotential line and stream line will be perpendicular to each other at the point of intersection.
What is sensitivity and thixotropy?
Higher is the sensitivity of soil, which means soil loses more of its strength on remoulding, larger will be the thixotropic hardening. We can say that because of remoulding soil becomes soft and if it is left undisturbed for some time soil regains some of its hardness.
What is streamline and equipotential line in irrigation?
What is equipotential line in soil?
A Flow net is a graphical representation of flow of water through a soil mass. Flow lines represent the path of flow along which the water will seep through the soil. Equipotential lines are formed by connecting the points of equal total head.
Where do the equipotential lines begin and end explain?
2. Electric field lines begin on positive charges and radiate away from them toward negative charges, where they terminate. 3. Equipotential lines are lines connecting points of the same electric potential.
What are equipotential lines?
Equipotential Lines: A line along which the potential head at all points is equal. Beside this, what are flow lines and equipotential lines? A flow net consists of two sets of lines, flowlines and equipotential lines. Flowlines or streamlines are the loci of the paths of flow of individual water particles.
Are all intersections between the streamlines and equipotential lines at right angles?
All intersections between the streamlines and equipotential lines are at right angles. Additionally, what are the characteristics of flow net? Properties of Flow net: Flow nets must satisfy the boundary conditions of flow field.
What is flow net in fluid mechanics?
If we will draw equipotential lines and stream lines for a fluid flow, we will see that both lines will intersect each other at right angle or orthogonally and will develop one grid or net and that grid will be termed as flow net. Flow net is a very important tool to analyse the two dimensional irrotational flow problems.
What is a stream function in fluid mechanics?
The existence of stream function proves a possible case of fluid flow, that can be either rotational or irrotational in nature. A stream function of a fluid satisfying a Laplace equation is supposed to have an irrotational flow. Equipotential Lines and Stream Lines in Fluid Mechanics
