it is generally recommended that pump operation should be maintained within +/- O 10 % of the best-efficiency point (BEP) flow rate. O 25 30 O 50 Pump curves relate head, hp. added by the pump and the flow rate, Q, through the pump. For commercial-size pumps, the curve also typically includes all of the following except O efficiency O NPSHR O power O NPSHA Placing two pumps in parallel will achieve which one of the following? Move the pump performance curve up Move the pump performance curve to the left Move the pump performance curve to the right Move the pump performance curve down Placing two pumps in series will achieve which one of the following? Move the pump performance curve to the right Move the pump performance curve up Move the pump performance curve to the left Move the pump performance curve down Partially closing a valve on a pipe attached to a pump will change which one of the following? pump curve system curve static head not enough information
