Tīmeklis2024. gada 9. dec. · The pump efficiency curve describes a pump’s efficiency over its whole operating range. Efficiency is represented in percentages on the right side of the curve graph. The efficiency curve’s peak characterizes the BEP, with efficiency diminishing as the curve arcs away, either right or left, from the BEP.

Tīmeklis2024. gada 31. aug. · Keep the speed constant and reduce or increase the flow from BEP fliw and note the pressure reading, convert pressure reading to head in m. There are software packages that can generate ideal QH curves for fixed RPM. Once you get the QH curve based ob BEP speed, then you can generate remaining curves with … Tīmeklis5. An electron is projected with an initial speed v 0 into a uniform field midway between two parallel plates. The field strength is such that the electron just misses the upper plate as it emerges from the plates, as shown in the figure alongside. Suppose that the electron is replaced by a proton with the same initial speed v 0.If the field strength … Tīmeklis2024. gada 11. febr. · Hi, There are a few ways. I would get the x and y axis, and use the setRange(double, double) function (there are other arguments you could use). So something along the lines of: Qh->yAxis->setRange(4, 13.2); //using your example. Qh->xAxis->setRange(xlower, xupper);. If you have multiple plotables, then you'd have … maysville local school district employment
