      <abstract xml:lang="ru">
        <p>Скоростная кинокамера ФП-22, примененная при изучении струи воды в условиях лаборатории Ленинградского горного института, да­вала съемку с частотой 25 000 и 50 000 кадров в секунду. Общая длина каждой пленки примерно 30 м при ширине кадра 5 мм и высоте 3,5 мм. Давление воды в насосе изменялось от 2 до 150 ати. При изучении каждой пленки в основном учитывались: 1) частота съемки (число кадров в секунду); 2) диаметр насадка (форма его не менялась); 3) давление воды; 4) наличие или отсутствие стабилизатора.</p>

        <p>The high-speed movie camera FP-22, used in the study of the water jet in the conditions of the laboratory of the Leningrad Mining Institute, gave shooting at a frequency of 25,000 and 50,000 frames per second. The total length of each film was approximately 30 m with a frame width of 5 mm and a height of 3.5 mm. The water pressure in the pump was varied from 2 to 150 ati. In studying each film, the following were mainly taken into account: 1) the shooting frequency (number of frames per second); 2) the diameter of the nozzle (its shape was not changed); 3) the water pressure; and 4) the presence or absence of a stabilizer.</p>
