Rotameters are fixed pressure, variable orifice flowmeters which are accurate to within ±2.5%.
But on that first hand, again, if you start with liquid water at a given, fixed pressure, and you lower the temperature, that will cause the water to immediately freeze!
Therefore, in the present study, we used neurally controlled PS (PSN), where the EAdi was used to initiate and terminate the breath, but with a targeted, fixed pressure.
Boundary conditions are applied as a slip or non-slip velocity function at the outside of the fixed grid geometry and initial conditions are applied as a fixed normal velocity or a fixed pressure and a fixed or a free shear velocity.
In case, any well pressure goes above the maximum BHP limit, the operating constraint switches from fixed injection rate to fixed pressure constraint to ensure that the injection pressure remains below the formation fracture pressure limit.
Permeability may be determined by either a fixed pressure drop or fixed flow rate experiment, with results presented from the fixed pressure drop approach by imposing a small gravity head of the flowing liquid; liquid flow is gravimetrically measured.
Three geometric parameters, including channel number, channel aspect ratio, and width ratio of channel to pitch, are simultaneously optimized at fixed inlet volume flow rate, fixed pumping power, and fixed pressure drop as constraint condition, respectively.
The optimal designs of MCHS based on minimum thermal resistance is performed at one or more constraint conditions of fixed inlet volume flow rate, fixed pressure drop and fixed pumping power.
Temporal changes of mesospheric temperature are larger at fixed heights than at fixed pressure levels as shown in Figure 4.
The ability of dense membranes to withstand high transmembrane pressure differentials allows the absorbent to circulate in a closed loop system at a fixed pressure set independently of the syngas pressure.
