- two pumps must work with them at the same time but if the first pump start the second pump must delayed for some time to start also , with motor rated power = 90 KW and rated voltage = 380 V and rated power factor = 0.85 lag please draw the power and control circuit for it and determine all circuit components parameters that you use it
