påføringstrykk

påføringstrykk, also known as withdrawal pressure, is a phenomenon that occurs when a fluid or gas is pumped into a pressurized system or a reservoir. When the pumping action is stopped, the pressure at the outlet of the pump remains relatively constant, but the pressure at the inlet decreases.

This decrease in pressure creates a difference in pressure between the inlet and outlet of the pump, which causes the fluid or gas to flow back into the reservoir or the supply system. The rate at which this occurs depends on the viscosity of the fluid, the diameter of the pipe, and the difference in pressure.

påføringstrykk is an important consideration in many fields, including the oil and gas industry, where it can affect the accuracy of measurements and the efficiency of production. In the context of injection and withdrawal of fluids from wells, påføringstrykk can be a major factor in optimizing production rates and preventing damage to equipment.

påføringstrykk has also been studied in the context of water supply and purification systems, where it can affect the quality of the water and the efficiency of treatment processes. Overall, påføringstrykk is an important concept in understanding the behavior of fluids and gases in various systems, and its study can lead to improvements in the design and operation of these systems.

The term påføringstrykk is Norwegian, and it translates to "withdrawal pressure" in English. The phenomenon itself is known by various names in different fields, but it is always related to the decrease in pressure at the inlet of a system after pumping has stopped.
