Pump and system curves can provide the efficiency or shaft power for a trimmed impeller. If these curves are not available, affinity laws can be used to predict the variations in pumping performance with changes in the impeller diameter: Q 2 / Q 1 2 / 1 H 2 / H 1 2 / 1)2 bhp 2 WebAffinity laws are used to predict what effect speed or impeller diameter changes have on centrifugal pump. Affinity laws state that for the same impeller diameter, if the pump speed is changed, flow rate is directly proportional to the speed, whereas the head is directly proportional to the square of the speed. crossfire motorcycles newcastle WebJan 7, 2024 · Unlike with a positive displacement pump, which gives us a fixed displacement per revolution regardless of pump discharge head, centrifugal pump performance is dictated by the affinity laws. For centrifugal pumps, the affinity laws state that: Flow is proportional to shaft speed or impeller diameter. Q 1 /Q 2 = (N 1 /N 2) or (D … Webthe impeller diameter on the centrifugal pump performance. The diameter was assumed based on the specification of the centrifugal pump as shown in table 1. The impeller … crossfire motorcycles review WebJan 15, 2014 · Affinity laws provide key insights about how centrifugal pumps work. However, as with all shortcuts, you must understand their limitations to prevent unexpected problems. Let's first consider the head affinity law. It states that pump head, h, varies with impeller diameter, d, squared: h 1 /h 2 = d 1 2 /d 2 2 (1)
