Russian term or phrase: разрыв давления
В этом реальном предельном случае (непроницаемый агрегат) давление за агрегатом будет заведомо меньше давления в удалении от агрегата, а не больше его, как это следует из... Однако сама идея замены агрегата одной или несколькими проницаемыми плоскими или иными фигурами, на которых происходит разрыв давления и сосредоточенный отбор мощности, оказалась весьма продуктивной.

Не совсем понятен смысл. Это скачок давления?

Спасибо!

pressure differential


Explanation:
The text in question mentions Δp several times, which is a pressure differential. For example,
В расчете задается относительная скорость потока через пластину U/U1, в результате получается относительный пе-репад давления 2Δp/ρU12и коэффициент мощности (эффек-тивности)Cp= 2ΔpU/ρU13

Delta P (ΔP), pressure difference or differential pressure usually refers in the technical world to the drop of pressure in a piping system, a heat exchanger or another machine, where a liquid is passing through.
The delta symbol Δ, is the fourth letter in the Greek and the Coptic alphabet. Delta / Δ is used as a mathematical symbol, which represents the „difference“ between two values.

neutral  mk_lab: Pressure differential (infinitely small discontinuity) is designated as dP but not Δp - real finite discontinuity /// Jump/drop is also possible option. But not "differential"
31 mins
  -> I mean Δp in the sense of a pressure jump.
