Способ позволяет измерять величину эффективных площадей любых по форме неплотностей. К одной стороне плоскости, в которой измеряют неплотность, герметично присоединяют испытательную камеру, в нее подают испытательное вещество в количестве, обеспечивающем его расход через неплотность. Температуру в камере и снаружи неплотности вдоль всей ее поверхности выравнивают и поддерживают одинаковой. Измеряют расход вещества, перепад давления и температуру в камере. Величину эффективной площади неплотности рассчитывают по формуле
Figure 00000001

где Fэ - эффективная площадь неплотности, м2; W - расход испытательного вещества через объект (кг/с); ε - коэффициент сжимаемости; r - плотность испытательного вещества в камере (кг/м3); DP - перепад между внутренним давлением в камере и давлением снаружи (Па).The method allows to measure the value of the effective areas of any form of leaks. To one side of the plane in which the leakage is measured, a test chamber is hermetically attached, a test substance is fed into it in an amount that ensures its flow through the leakage. The temperature in the chamber and outside leaks along its entire surface level and maintain the same. Measure the flow of matter, pressure drop and temperature in the chamber. The value of the effective area of leakage calculated by the formula
Figure 00000001

where F e - the effective area of leakage, m 2 ; W is the flow rate of the test substance through the object (kg / s); ε is the compressibility factor; r is the density of the test substance in the chamber (kg / m 3 ); DP is the difference between the internal pressure in the chamber and the pressure outside (Pa).
