1. Key points

Hydraulic resistance along the length of the pipeline is due to the forces of internal friction and is directly proportional to the length of the flow. Head loss h l , caused by hydraulic resistance along the length of a cylindrical pipe, is determined by the Darcy formula

Where λ is the coefficient of hydraulic friction;

l- pipeline length;

d– pipeline diameter;

V is the average flow velocity over the cross section.

In laminar motion, the friction coefficient λ is a function of the Reynolds number (Re) and is determined by the formula

In the turbulent mode of motion, three zones (areas) of resistance are distinguished: hydraulically smooth pipes, zone hydraulically rough pipes and transition zone. In the zone hydraulically smooth pipes the thickness of the laminar film (δ) formed along the pipe walls is greater than the height of the roughness irregularities (∆) on the pipe wall: δ > ∆. In this zone, the coefficient of friction (λch.) does not depend on the roughness of the pipe and is a function of the Reynolds number only. For Re< 10 5 коэффициент трения λ гл. может быть определён по эмпирической формуле Блазиуса

In the zone hydraulically roughened pipes the thickness of the laminar film is less than the height of the roughness protrusions (δ< ∆). Коэффициент трения для зоны шероховатых труб (квадратичной зоны) λ кв. зависит только от относительной шероховатости и может быть вычислен по формуле


λ sq \u003d 0.11 () 0. 25,

where is the relative equivalent roughness.


In the transition zone (zone of mixed friction), the thickness of the laminar layer is approximately equal to the height of the roughness ridges (δ ∆), so the friction coefficient λ see tr. in this zone is a function of both the Reynolds number and the relative roughness. It can be calculated by the generalized Altshul formula

λ see tr. = 0.11( + ) 0.25 .

Goal of the work

1. Determine experimentally the value of the coefficient of hydraulic friction.

2. Determine the mode of fluid movement and select the calculation formula corresponding to the mode (and resistance zone).

3. Description of the laboratory setup

The scheme of the laboratory installation (Fig. 1) includes: 1-pressure tank, in which the water level is maintained at a constant height; 2 - valve; 3 - pipeline with inner diameter d = 20mm; 4, 5-piezometers connected to the working section of the pipeline with a length l; 6 - valve; 7-measurement tank with water-measuring glass 8 for flow measurement; 9 - drain cock.

Chapter 1

Physical culture and sports in the social and professional training of students

The concept of "culture" can be defined as the degree of disclosure of the potential of the individual in various areas of human activity. Physical culture is represented in society by a combination of spiritual and material values.

The history of physical culture and sports goes back thousands of years. Physical culture is part of the general culture of society, aimed at strengthening and improving the level of health.

In evolutionary terms, all components of the human body developed and improved on the basis of movement. The formation of physical culture and its development is largely due to the material conditions of society.

Many changes in the internal structure of each sport often depended and depend on the progress of technology, on the results of scientific discoveries.

Physical culture and sports in modern society are complex multifunctional phenomena. The main indicator of the physical condition of a person is his health, which ensures the full performance by a person of all vital functions and forms of activity in certain specific conditions. The health-improving orientation of physical culture and mass sports is the regularity of their functioning. A healthy country's gene pool can ensure the good physical condition of future parents.

Physical education involves the optimal development of all motor qualities. The main quality of an athlete in his physical fitness is versatile training.



The main goal of the harmonious formation of a person lies in the joint upbringing and development of the physical and spiritual principles of a person's personality. Physical perfection is a historically determined level of health and comprehensive development of people's physical abilities. Signs and indicators of physical perfection are determined by the real needs and conditions of society at each historical stage and therefore change as society develops.

Physical culture and sports play a special role in preparing for the active work of the young generation. It is known that a well-trained person, strong, enduring, dexterous and quick, possessing a variety of skills and abilities, will quickly and successfully adapt to new working conditions.

Physical culture and sports are the means of strengthening peace, friendship and cooperation between peoples. National sports are used as a means of physical education. International sports meetings bring up respect for representatives of other countries, for their customs, allow creating an atmosphere of mutual understanding between people, and encourage international cooperation.

In the field of physical culture and health improvement, personal and public interests are brought together and balanced. Modern sport is of great importance in the development of human contacts. The physical culture of a person is characterized by the level of his education in the field of physical culture. The formation of the character and behavior of a person, the characteristics of his personality are largely determined by the social conditions, the environment in which he lived and lives.

One of the main and difficult tasks of the discipline "Physical Culture" in a higher educational institution is the formation of a meaningfully positive attitude towards physical culture and sports in all students. from the presence or absence of knowledge in the field of physical culture and sports.The main criteria for the formation of a person's physical culture are set out in the state standard.

The natural forces of nature are used as means of physical culture, and physical exercises are the main specific means. Physical exercise is the most effective way to relieve mental fatigue. In physical culture practice, physical exercises are used in the form of various exercises, gymnastics, various sports, games and tourism.

Factors of personal and public hygiene are an inextricable part of physical culture. Basic physical culture is a component of physical culture. . Basic physical culture serves as the foundation for specialized types of training (professional-applied, sports, etc.).

Sport is an integral part of physical culture, a means and method of physical education based on the use of competitive activity and preparation for it, during which the potential capabilities of a person are compared and evaluated.

A component of physical culture is also the "background types" of physical culture, such as hygienic and recreational physical culture. Recreational - usually presented in the mode of extended active recreation (sports entertainment with non-strictly normalized and non-forced physical activity, as well as hunting, active types of fishing, active-motor types of tourism).

Tourism is an essential component of physical culture. Active types of tourism (hiking, cycling, water, etc.) are effective physical exercises, which very often have not only health-improving, sports, but also professional-applied character. Professional-applied physical training is associated with the process of profiled (directed) use of physical culture and sports means to prepare for a future profession.

"Background" types of physical culture (or, as they are otherwise called, "small forms") have a less profound effect on the physical status and development of the body, but they play an important role in the operational regulation of the current functional state of the body, create certain prerequisites for maintaining daily activity man in modern conditions of life.

Physical education is a pedagogical process aimed at the formation of a person's physical culture as a result of pedagogical influence and self-education. A component of physical education is psychophysical training. Realization of each component of physical culture is closely connected with the process of physical education. The practical implementation of physical education always has a target setting for a longer or shorter period of a person's life, which involves the development of program-normative foundations of physical education for each period.

The main legislative instrument of the discipline "physical culture" is the order of the Ministry of Education of the Russian Federation. The physical culture program includes the following main sections: organizational and methodological, theoretical, practical, control sections.

Mandatory types of physical exercises for inclusion in the work program for physical culture are; individual disciplines of track and field athletics (100 m run - men, women, 2000 m run - women, 3000 m run - men ..), swimming, sports games, cross-country skiing, professional-applied physical training (PPFP).

One of the conditions and criteria that ensure the success of the process of physical education is the regularity of attending compulsory practical classes in the academic discipline "Physical Culture".

Training sessions (I-IV courses) are held in the form of: independent, theoretical, practical and control work.

For practical training in the academic discipline "Physical Education", on the basis of a medical report, students are distributed into three educational departments: basic, special, sports.

Students who have not passed a medical examination are not allowed to practical training sessions. Those who, for health reasons, are exempted from practical training in physical education for a long time, are also enrolled in a special educational department for mastering the available sections of the program. The same department enrolls students assigned to special practical classes in groups of therapeutic physical culture (LFK).

The total average scores of tests of the practical section were established: the average score of 2.0 points - "satisfactory", 3.0 - "good", 3.5 - "excellent". All students of the special department at the end of each semester submit abstracts. At the end of the course of the discipline "Physical Education" in all educational departments, an exam is held. The final certification of students is carried out in the form of testing on the theoretical and methodological sections of the program.
