The phrase "activation pressure" is correct and usable in written English.
It can be used in contexts related to science, engineering, or psychology, where it refers to the pressure required to activate a process or mechanism.
Example: "The activation pressure needed to initiate the chemical reaction was higher than initially expected."
Alternatives: "trigger pressure" or "initiation pressure".
Subsequently, this allowed the geometric parameters to be modified to significantly reduce activation pressure and, thus, pump energy consumption.
Also, the inertia and the activation pressure of the venting elements can influence the explosion pressures.
However, the predictive results calculated according to both NFPA 68 and EN 14491 tend to be conservative as the vent diameter decreases and the static activation pressure increases.
In this study, the DIN-Report 140 has been analysed by calculating a wide range of cases, including different silo dimensions, materials (barley and wheat flour) and values of inertia and activation pressure of the venting devices.
Secondly, Yoda1 sensitized mPiezo1 to activation by pressure as indicated by a leftward shift in the current pressure relationship, reducing the half maximal activation pressure (P50) by about 15 mm Hg.
This effect was more pronounced for small vents and high static activation pressures.
Furthermore vented dust explosion experiments were done for two different dispersion methods and two static activation pressures.
Vented hybrid mixture explosions were conducted in a 20-L chamber with different venting diameters and static activation pressures.
Three vent diameters of 28, 40, and 60 mm were chosen to carry out the venting experiments at static activation pressures ranging from 0.66 to 2.80 bar.
The alloy retained both the low activation pressures and fast absorption desorption rates even after more than 2 years of exposure in open air.
To assess our model, some numerical examples are presented, showing typical features of hydraulic fracture phenomenon, including the characterization of the fault-activation pressure and specific crack path growth, allowing for kinking and bifurcations.
