extraction pressure

Powerful electric pumps replace manual levers, permitting a consistent espresso extraction pressure.

The influence of extraction pressure, crown aspect, height into the crown, tree age, time of year and day, and soil chemistry on the ion concentrations in xylem sap are discussed.

The Law of the Ellipse, or Stodola's cone law, provides a method for calculating the highly nonlinear dependence of extraction pressures with a flow for multistage turbine with high backpressure, when the turbine nozzles are not choked.

The other parameters for design are the temperature and pressure at the stage group intake, and , respectively the extraction pressure at the stage group outlet (the symbol is used for the pressure after a stage nozzles, pressure does not interfere in relations here).
