I then set the pump to again. This was giving me a flow rate of ~1030-1060 l/h / 17.2-17.5 l/m and the flow rate being measured by the heat meter does tally pretty well with this at ~16.8 l/m and also tallies well against historical flow rates.

A major issue with the existing vanadium redox flow battery (VRFB) models is the inaccurate prediction of the open circuit voltage (OCV), which results in a discrepancy of 131 to 140 mV in predicted cell voltages when compared to experimental data. This deviation is shown to be caused by the incomplete description of the electrochemical …

Background: The invasive physiologic index such as fractional flow reserve (FFR) or instantaneous wave-free ratio (iFR) is used in clinical practice to identify ischemia-causing stenosis and to guide treatment strategy. We investigated clinical and angiographic characteristics of lesions with discrepancy between FFR and iFR. Methods: From the …

Several factors may influence the discrepancy, researchers say, including snowmelt, interaction with groundwater, flow and discharge rates, solar radiation, wind and humidity. But even after factoring out those elements, the scientists were surprised by the cooler-than-expected maximum, mean and minimum temperatures of the streams.
Prior myocardial infarction showed a statistically significant association with increased classification discrepancy between quantitative flow ratio and fractional flow reserve (odds ratio 3.16 (95% confidence interval: 1.29-7.75), P =.01). The area under the receiver-operating characteristic curve of quantitative flow ratio showed no ...

We construct a Wasserstein gradient flow of the maximum mean discrepancy (MMD) and study its convergence properties. The MMD is an integral probability metric defined for a reproducing kernel Hilbert space (RKHS), and serves as a metric on probability measures for a sufficiently rich RKHS. We obtain conditions for …

CORVALLIS, Ore. – Oregon State University scientists have created a tool that can predict the flow rate of Arctic rivers with a surprising degree of accuracy based on the makeup and abundance of bacteria in the water. Their successful "genohydrology" approach is important because many Arctic rivers are remote and quite rugged, making …

It is a good practice to generate a standard ore flow balance sheet indicating all sources of metals such as gold. An explanation of all recoveries and losses along the flow must be accurately captured in the standard ore flow sheet. An example of an ore accounting sheet showing the sources of ore is in table 2.1 24 Table 2.1 Ore flow balance ...
For example, if you connect multiple lateral pipes to a valve, the Size Lateral Pipes dialog box will only display the flow rate/GPM and pipe size information for the last segment processed.. After you click OK, all lateral pipes will be sized correctly, and the valve callout will reflect the correct total flow/GPM.
