## Which equation represents free vortex flow?

Equation (14.15) can also be derived by a straight forward application of Bernoulli’s equation between any two points at r = ra and r = r. In a free vortex flow total mechanical energy remains constant.

## Can Bernoulli’s equation be applied to a forced vortex flow?

In forced vortex flow external supply is required to maintain the constant flow (constant angular momentum). In free vortex flow the velocity is remain same in the flow i.e. no external torque is required. In free vortex flow, Bernoulli’s equation can be applied.

## How do you calculate vortex velocity?

The associated scalar vorticity is a delta function in the plane, and the induced velocity is obtained from the Biot-Savart law. For a point vortex at the origin this reduces to the radial velocity field u(x) = K2d ∗δ = K2d(x).

## What is forced flow?

Forced flow is flow done by any mechanical or human machinery like a fan or a pump, in the natural flow the fluid is in motion by natural principles like buoyancy effect, the warmer fluid rises and the cooler falls. The flow caused by wind is natural.

## What is vortex in math?

Vortex math is a system of numbers which explains the essence of form as a sphere with a vortex. The numbers reveal a spiral line and a curved plane. The numbers in this spiral line describe the form of a vortex , the vortex describes an inward contraction with its equal expansion which is the inner form of a torus .

## How do I find my vortex strength?

The product of mass flow rate and circulation = Energy (ML2T-2). So if you have a flow with mass flow rate of X kg/s in a flow with circulation of Y m2/s, then the vortical flow has a strength equivalent to XY kgm2s-2 = XY Joules.

## What is vortex field?

Vortex fields are said to originate from vortices. 2.1 Electric Source-Fields. Electric source-fields exist in the environment of electriC char- ges at rest (electrostatic charges, fixed or localized charges). The existence of these fields can be demonstrated via their forces on objects brought into the field.

## What is the difference between forced flow and natural flow?

A fluid flow is said to be natural or forced, depending on how the fluid motion is initiated. In forced flow, a fluid is forced to flow over a surface or in a pipe by external means such as a pump or a fan. In natural flows, any fluid motion is due to natural means such as the buoyancy effect.
