Webthe flow rate measured at a backpressure of 1798 psi was not less than the flow rate produced at 1401 psi with nearly the same injection pressure. That is, because the apertures of flow paths were dilated with a higher mean reservoir pressure, the overall flow impedance declined enough to maintain the level of production flow in spite WebFlow resistors in a fluidic circuit are the analogous elements to electrical resistors in an electrical circuit. In these analogous circuits, the pressure [mbar] corresponds to the voltage [V], the flow rate [µL/min] to the electrical current [A] and the flow resistance [mbar·min/µL] (or hydrodynamic resistance) to the electrical resistance ...
WebSep 12, 2024 · Substituting into Equation 3.20.1 we obtain: (3.20.2) P a v + = V 0 + 2 2 Z 0. This is the time-average power associated with the incident wave, measured at any point z < 0 along the line. Equation 3.20.2 gives the time-average power associated with a wave traveling in a single direction along a lossless transmission line. WebApr 11, 2024 · This study proposes a low-cost, portable paper-fluidic vertical flow assay bacterium counter with high accuracy. We designed sensors with low fabrication costs based on e-beam evaporation and three-dimensional printing based on the impedance measurement principle.

WebAirflow Resistance. Air flow resistance is defined as the ratio of static gas pressure between both sides of material to the airflow speed. Flow resistivity is defined as the airflow resistance within unit of thickness and it reflects the air permeability through porous materials [25]. The higher the airflow resistivity, the less air ... WebThe input impedance of an electrical network is the measure of the opposition to current (), both static and dynamic (), into the load that is external to the electrical source network. …
