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: for a derivative element, the quotient of the value of the output variable to the value of the time derivative of the input variable; Name: derivative action coefficient
