what is the physical significance of stream function?

The stream function is defined for incompressible (divergence-free) flows in two dimensions – as well as in three dimensions with axisymmetry. ... The stream function can be used to plot streamlines, which represent the trajectories of particles in a steady flow.

Electromagnetic flowmeters use Faraday's Law to determine the flow of liquid in a pipe. Whereby, the flow of a conductive liquid through the magnetic field causes a voltage signal to be sensed by electrodes located on the flow tube walls. The voltage generated is proportional to the movement of the flowing liquid.

std::ifstream. Input stream class to operate on files. Objects of this class maintain a filebuf object as their internal stream buffer, which performs input/output operations on the file they are associated with (if any). File streams are associated with files either on construction, or by calling member open .

The flow of time is the flow of energy is a simple statement but one that places time on the same footing with space. It takes time to distinguish a spatial loci from another, i.e. to move energy from one distinct density to another. The evolving space–time is energy–momentum transfer process.

The fseek() function is used to set the file position indicator for the stream to a new position. This function accepts three arguments. The first argument is the FILE stream pointer returned by the fopen() function.

The Laplacian occurs in differential equations that describe many physical phenomena, such as electric and gravitational potentials, the diffusion equation for heat and fluid flow, wave propagation, and quantum mechanics. The Laplacian represents the flux density of the gradient flow of a function.

There are three physical properties of fluids that are particularly important: density, viscosity, and surface tension. Each of these will be defined and viewed briefly in terms of molecular concepts, and their dimensions will be examined in terms of mass, length, and time (M, L, and T).

The pump delivers a rate of flow. The single function of the pump is to take fluid from one place and put it somewhere else. Pressure is the result of resistance to flow. ... A fixed-displacement pump is the simplest type of hydraulic pump.

It is used to perform read and write operations in file permanently. Java uses streams to perform these tasks. Java I/O stream is also called File Handling, or File I/O. It is available in java.io package. Java.io package provides classes for system input and output through files, network streams, memory buffers, etc.

4.7 Physical significance of the wave function. The wave function ψ associated with a moving particle is not an observable quantity and does not have any direct physical meaning. ... However, this can represent the probability density of locating the particle at a place in a given instant of time.

A River and a Stream are both fast moving bodies of water, but a river is called a River because it is larger, deeper, and longer than a stream, as for a stream it is much than a river not as deep, some you can even walk across. Another difference is that a stream is a small flowing water.

“ The difference lies in movement and flow. Process implies a flow of related activities that work together to achieve an objective. On the other hand, a function implies a discrete action that produces a result.

C++ Library - <fstream> This data type represents the file stream generally, and has the capabilities of both ofstream and ifstream which means it can create files, write information to files, and read information from files.

Thus, the terms discharge, streamflow, and runoff represent water with the solids dissolved in it and the sediment mixed with it. Of these terms, discharge is the most comprehensive. ... The differentiation between runoff as a volume and streamflow as a rate is not accepted.

4.7 Physical significance of the wave function. The wave function ψ associated with a moving particle is not an observable quantity and does not have any direct physical meaning. It is a complex quantity. ... However, this can represent the probability density of locating the particle at a place in a given instant of time.

The changes in physical characteristics like temperature, transparency and chemical elements of water such as dissolved oxygen, chemical oxygen demand, nitrate and phosphate provide valuable information on the quality of the water, the source of the variations and their impacts on the functions and biodiversity of a ...

There are two basic types of stream defined by Java, called byte stream and character stream. The byte stream classes provide a convenient means for handling input and output of bytes and character streams provide a convenient means for handling input and output of characters, respectively.
