Analysis of magnetohydrodynamic phenomena in a single spatial electromagnetic field

. The paper presents the results of the analysis of the disinfection of water by a pulsed single spatial electromagnetic field. The origin of the fluid pressure in the pipe is calculated and graphically presented as the interaction of a single spatial field and the current of moving charges. It is proved that a single spatial field enhances the process of dissociation of water in a liquid solution. The orbital electrons of two hydrogen atoms and one oxygen atom of water create a strong inhomogeneous electric field around themselves, which leads to the separation of the liquid solution and the compounds contained in it into elements. The purpose of the work is to study magneto hydrodynamic phenomena in a single spatial electromagnetic field disinfection of water by a single spatial electromagnetic field, The theory of a single spatial field involves the interaction of four fields of pulsed electromagnetic, pulsed electric, permanent magnetic and gravitational. The theory of a single spatial field is substantiated, which allows us to consider the issues of effective disinfection, desalination and purification of water, as well as to study the effects of electric, magnetic fields and electromagnetic waves on physical, chemical and biological processes occurring in liquids.


Introduction
Rational use of water resources around the world, namely drinking, industrial, municipal, economic and waste water, improving its quality, purification and disinfection technology is an urgent problem.One of the main tasks of the national economy is the creation of devices for disinfection and desalination of water with high productivity and efficiency, high reliability and energy saving, which is becoming important [1][2][3][4][5][6][7][8][9][10].To develop devices based on a single spatial electromagnetic field, it is necessary to solve the following tasks:to analyze magneto hydrodynamic phenomena in a single spatial electromagnetic field; -to investigate the interactions of charged particles in a single spatial electromagnetic field.Let a viscous incompressible conducting fluid move in a transverse magnetic field in a cylindrical channel of width d along the Z axis with a velocity (Figure 1).
Let's find the velocity distribution over the cross section of the channel.Due to the movement of the liquid in the external field

Materials and methods
Let's find the velocity distribution over the cross section of the channel.Due to the movement of the liquid in the external field We get: Where p -pressure;  -viscosity of the liquid;  -current density.
According to Ohm 's law in differential form: ) ( From here: Where we will find:

Results and Discussion
In an arbitrary section of a pipe and a fluid whose center of gravity is at a height h from the zero reference level, the following relation must be fulfilled Where р -external pressure; vthe speed of movement through this section;  -liquid density.
From an energy point of view, pressure p is the work performed by external forces on a single volume of liquid: For two arbitrary sections of the fluid flow, the law of conservation of energy for a fluid is observed: A liquid, being in a closed space (a non-conducting pipe), experiences pressure from a single spatial field, which is determined by the force coming on a unit of the external surface: Where F -the force acting from the side of a single spatial field; I -Conduction current; H -field strength;  -thin layer length.
On the other hand: Where d-pipe radius.However, Maxwell's idea of the field pressure seems too formal -it is easier and clearer for us to imagine the origin of such pressure as the interaction of a single spatial field and the current of moving charges.
The liquid molecule has a large dipole moment This is the cause of electrolytic dissociation.Consequently, a single spatial field enhances the process of dissociation of water in a liquid solution.The orbital electrons of two hydrogen atoms and one oxygen atom of water create a strong inhomogeneous electric field around themselves, which leads to the separation of the liquid solution and the compounds contained in it into elements.[11][12][13][14][15][16][17][18].
If the liquid is moving at a speed of  across the field lines of force with induction B , then there is an electromotive force of induction in the volume of the liquid: Where l is the length of the liquid section in the pipe.Resistance of the liquid phase: Where  -specific conductivity in a liquid: According to Lenz's rule, the induced current interacts with the field in such a way that the resulting interaction force prevents the movement of water.Thus, in addition to the usual hydrodynamic forces, electromagnetic forces also act in the liquid [19][20].Magnetic induction of the field of induced currents: The force acting from the magnetic field: This force can be compared to the friction force:  l Where  -the viscosity coefficient of the liquid.
Pressure resistance force: The ratio of ampere strength to resistance is called the Stewart criterion: With large Hartmann or Stewart numbers, the viscosity of the liquid recedes into the background, the resistance to movement arises mainly due to the interaction of the liquid with a single spatial field.
At the same time, the water in the solution is saturated with negative oxygen ions, that is, it becomes more transparent.Positive hydrogen ions leave the liquid solution.

Conclusion
Based on the theory presented, the following conclusions can be drawn:  A single spatial field allows you to disinfect and purify water. Pulsed electric and magnetic fields allow water to be saturated with oxygen ions. The spatial field allows you to remove heavy metals from the water. With the help of pulsed electromagnetic fields, it is possible to disinfect water without the use of reagents, destroy viruses, heat liquids by increasing internal energy, create environmentally friendly devices with high efficiency. The use of a single spatial field in the development of technology and technological means of disinfection and purification of water can significantly save energy and material resources in desert and semi-desert conditions.

force with the resistance force gives us the Hartmann criterion: flows through a pipe across a single spatial field, then at small Hartmann or Stewart numbers, the field has little effect on the nature of the flow, and resistance to movement arises mainly due to the viscosity of the liquid.
