I need to determine the minimum flow rate of liquid required to cool a random wound 3 phase induction motor (150Hp, 575v). This will be a submerged pump which will divert a +40C fluid through the motor housing along with through the air gap. How can I relate the required flow per motor watt loss in order to maintain a class F temp limit? This fluid temperature is fixed and cannot be changed.
