But first, let’s see how pump curves are created. The pump curves we see in pump manufacturers’ catalogs are a visual representation of test data collected in their labs. To collect this data, a technician connects the pump to a test station, similar to the one depicted in Figure 1,...

BEHIND structure that lets you set various parameters regarding how to use the blur effect on your window. The most important one of the parameters is a region, which is a GDI term that describes an arbitrarily shaped area that is usually constructed out of a series of lines and curves....
A large-scale, vaned-voluted centrifugal pump can be applied as the key component in water-transfer projects. Pressure pulsation will be an important factor in affecting the operation stability. This paper researches the propagation and spatial distribution law of blade passing frequency (BPF) and ...
The blue curves represent the Poisson probability, Pn(t), that n He atoms have bound to the ion in the interval [0,t], scaled such that the peak of P2(t) matches the peak of the Na+(He2). b, Black dots: the sum of the ions yields shown in a0–a25, that is, \({{\rm{S...
This report presents the Harespod dataset, an open dataset for high altitude hypoxia research, which includes respiration and SpO2 data. The dataset was collected from 15 college students aged 23–31 in a hypobaric oxygen chamber, during simulated altitu
Roots pump belowground water vertically upward, it then transpires through the leaves and the resulting humidity rises to the atmosphere to form clouds. Over the Amazon this biotic pump is so powerful that the resulting pressure difference attracts additional humidity from the Atlantic, which in ...
