methanol solution (°C), Mj is the molecular weight of the inhibitor j, and yj is the weight percent concentration of inhibitor j, and kj is a constant value for different inhibitors, typical values of k are 2335, 2700 and 5400 for methanol, ethylene glycol and triethylene glycol, ...
During numerical simulation, the permeability was assumed to be constant across the entire core sample within each very short time step and was evaluated for each time step by the second-order permeability model. The average pressure of the core at the end of the previous time step was used ...
Modern vehicles have advanced cruise control (ACC) systems to keep the vehicle at a constant speed in many conditions. A 2024 study demonstrated these systems can improve fuel savings by up to 22% in urban areas. Minimize idling. The Department of Energy estimates that idling a vehicle burns ...
different regions over this extensive parameter window. Additionally, it should be remembered that thelight intensitygenerated in any region depends on the product of the density of gas atoms (this is constant for a given pressure and gas temperature), the number of electrons or ions with ...
the ligand of MOF must be deprotonated prior to forming metal-ligand bonds during MOF crystal growth55. Since PDC and BDC have different pKa values (2.8 and 3.7, respectively)56, PDC linkers have slightly higher dissociation than BDC linkers. This outcome could facilitate crystal growth due to ...
We find that for the different values of w used in the experiments, the corrections used to estimate the virtual origin of the plume are small, with x0/L = 0.023 ± 0.018 relative to the horizontal length of the plume in the tank, L, and z0/H = 0.006 ± ...
at a constant sampling interval which must coincide with the sampling interval that is used to read out the raw signals from the SGP40/41 sensor. The default sampling interval applied in the algorithm is 1 s. If your sampling interval is different, please use the constructor variant allowing ...
(N–S) equations into the slip and transition flow regimes. Comparisons of different values and formulations of the first- and second-order slip coefficients and models reveal the discrepancies arising from different definitions in the first-order slip coefficient and various approaches to determine ...
Gas plant economics are based on the price of intermediate and finished products. As such, the composition of the intermediate and finished products exiting the plant vary due to their market driven commodity values. At the exit of the gas processing plant, the transmission quality natural gas (...
This is different from most other chromatographic systems in which the mobile phase may play an important role in the separation based upon its chemical properties. The choice of a carrier gas is limited based on the type of detector used, or when several gases may be suitable, on its ...
