ФИЗИЧЕСКИЕ СВОЙСТВА ЖИДКОСТЕЙ
Жидкостью называется физическое тело, способное изменять свою форму под действием сколь угодно малых сил, не дробясь на капли, т.е., как принято говорить, жидкость обладает текучестью.
Жидкости делятся на два класса: капельные и газы. В курсе «Гидравлика» изучаются капельные жидкости, называемые просто жидкостью.
Плотность
Одной из основных характеристик жидкости является ее плотность r, которая характеризует распределение массы жидкости М по объему W:
(1)
Так, для дистиллированной воды при 4°С плотность составляет 1000 
.
Применяют еще относительную плотность d, равную отношению плотности жидкости к плотности воды при 4°С, т.е. 
.
