While under-predicting total pressure drop, the analytical equation does capture prevailing trends of the effects of channel dimensions on the pressure drop and can be used for rapid evaluation of numerous tradeoffs from a system perspective.
The coatings were sputter-deposited on silicon and steel substrates by a reactive RF-magnetron process under variation of total pressure, reactive gas flow and RF-power.
The rate of CaO sulfidation decreased with the increase in total pressure under constant H2S partial pressure.
In the optimized serpentine channel design, the maximized oxygen transport ratio is predicted to be 0.718 at the interface between the GDM and catalyst layers under the constraint of total pressure drop.
The oxygen contamination conditions have been obtained at different oxygen partial pressures under low total pressure conditions (Knudsen regime), confirming that an oxide removal regime occurs under an oxygen partial pressure much higher than the equilibrium one (the "Effective Oxidation Pressure").
The plasma source generated reactive plasma just above the substrates through the abnormal glow discharge with a CH4/N2 mixture inlet under a total pressure of 750 Pa.
Si B C coatings were prepared by chemical vapor deposition (CVD) from CH3SiCl3/BCl3/H2 gas mixtures at 900 1000 °C and under low total pressure (5 kPa).
The optimal operating conditions for the production of light olefins were found to be 270 °C under the total pressure of 3 bar at the molar feed ratio of H2/CO = 2/1.
Prakash et al. [97] reported high-quality films with preferential (220) orientation obtained at a substrate temperature of 650 °C under a total pressure of 4.86 Pa with 1 % O2.
This result suggested that gas exchange rates of plants grown under low total pressure were not stimulated even with the enhancement of gas diffusion because the stomatal size and stomatal aperture decreased.
Follonier et al. (2013) found that when P. putida KT2440 was grown in medium supplemented with octanoate, the same gene was upregulated to a much lesser extent under elevated total pressure and elevated oxygen pressure (fold change of 1.59 and 1.7, respectively).
