Hard Electromagnet Problem?

A large electromagnet draws a current of 272.00 A at 262.00 V. The coils of the electromagnet are cooled by a flow of water ping over them. The water enters the electromagnet at a temperature of 23.00 �C, absorbs the Joule heat, and leaves at a higher temperature. If the water is to leave at a temperature no higher than 78.00 �C, what is the minimum rate of flow of water through the electromagnet? The specific heat of water is 4190 J/(kg�K).
