In a flow field the streamline and equipotential lines?
Victoria Simmons A line along which stream function (ψ) is constant is known as streamline. Equipotential line: A line along which Potential flow - Wikipedia
How are streamlines and equipotential lines related in a flow?
The streamlines ψ and equipotential lines Φ are mutually perpendicular to each other. The stream lines are so spaced that rate of flow Q is same between each successive pair of lines. The stream lines in flow net show the direction of flow and the equipotential lines join the points the equal velocity potential Φ.
What is the dot product of slopes of equipotential line and streamline?
Streamline is basically defined as the line along which the Streamline function (Ψ) is constant. Let us consider the equation of equipotential line and stream 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.
What is the value of angle between stream lines and equipotential lines at the point of intersection in the flow net?
Properties of Flow Net: The angle of the intersection between each flow line and the equipotential line must be 90° which means they should be orthogonal to each other.
What is flow along a streamline?
A streamline flow or laminar flow is defined as one in which there are no turbulent velocity fluctuations. ... These streamlines are drawn such that, at any instant in time, the tangent to the streamline at any one point in space is aligned with the instantaneous velocity vector at that point.

What is the difference between 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 do equipotential lines represent?
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.
What is the part represented by the stream lines?
Explanation: A streamline is defined as an imaginary line within the flow such that the tangent at any point on it indicates the velocity at that point. In a steady flow, the velocity of the particles is constant with time. Hence, the streamlines remain the same even after sometime.
Which of the following are the flow measuring devices?
The devices are: 1. The Venturimeter 2. The Pitot Tube 3. Orifice Plate or Orifice Meter 4.
What is the equation of Streamline?
Solution: a) Streamline: Here Ux=(1+At +Bt2) and Uy=x. Since the slope of the streamline (dy/dx) is the same as the slope (Uy/Ux) of the velocity vector.
What is Flow Net in soil mechanics?
Flow net represents the flow of water through a soil graphically. Applications include calculation of uplift pressure, exit gradient, heaving and pore water pressure.
How can we determine whether the flow is laminar or turbulent?
For practical purposes, if the Reynolds number is less than 2000, the flow is laminar. If it is greater than 3500, the flow is turbulent.
What do you mean by irrotational flow?
Irrotational flow is a flow in which each element of the moving fluid undergoes no net rotation with respect to a chosen coordinate axes from one instant to other. A well-known example of irrotational motion is that of the carriages of the Ferris wheel (giant wheel).
Why is equipotential important?
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.
What are flow lines and equipotential lines?
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.
What is equipotential surface Class 12?
Equipotential surface is a surface where all the points lying on the surface have the same electric potential. This means that a charge will have the same potential energy at every point on the equipotential surface.
Why minor losses occur in pipe flow?
Minor losses are local energy losses caused by the disruption of the flow due to the installation of appurtenances, such as valves, bends, and other fittings [5]. ... For pipelines of large lengths the energy losses are mostly caused by friction effect and the energy losses caused by fittings are minimal.
What is laminar boundary layer flow?
Abstract. Laminar boundary-layer flows occur when a moving viscous fluid comes in contact with a solid surface and a layer of rotational fluid, the boundary layer, forms in response to the action of viscosity and the no-slip boundary condition on the surface.
What is it called when both the source and sink are of equal strength?
Explanation: Doublet is the special case of source and sink with equal strength.
What is PATH line and streamline?
Streamlines are a family of curves that are instantaneously tangent to the velocity vector of the flow. These show the direction in which a massless fluid element will travel at any point in time. ... Pathlines are the trajectories that individual fluid particles follow.
What are the two types of flow?
Type of Fluid Flow. Fluid flow is generally broken down into two different types of flows, laminar flow and turbulent flow.
What is streamline flow and turbulent flow explain Stokes law?
In other words, in the streamline flow of a liquid, the velocity of every particle crossing a particular point is the same. ... This limiting value of velocity is called critical velocity. Turbulent flow. When the velocity of a liquid exceeds the critical velocity, the path and velocities of the liquid become disorderly.
