Flow rate triangle
WebSep 24, 2024 · The triangle representing the Rated Duty Point is the location where the System Resistance Curve that the pump is feeding, crosses the pump Head-Flow Curve. ... NPSHr will generally increase exponentially as flow rate is increased. Now you have a general understanding of how to read a centrifugal pump performance curve. WebThe flow rate measurement in a rectangular weir is based on the Bernoulli Equation principles and can be expressed as: q = 2/3 cd b (2 g)1/2 h3/2 (1) where. q = flow rate (m3/s) h = elevation head on the weir (m) b = width of the weir (m) g = 9.81 (m/s2) - gravity. cd = discharge constant for the weir - must be determined.
