Description: Relationship between the head of the pump to the flow rate at certain working/design conditions of speed and pumped material.; Name: Pump characteristic curve
Description: pump H(Q) curve where the maximum head and shut-off head are coincidental, and the total head declines continuously as the rate of flow increases; Name: Pump H(Q) curve
Description: Determined ten times the logarithm to the base 10 of the ratio of the sound energy, j, to a reference value, j0, expressed in decibels; Name: Sound energy level
