Water at 60F enters a 1-in.-ID tube that is used to

cool a nuclear reactor. The water flow rate is 30 gal/min.

Determine the total heat transfer, the exiting water temperature, and the wall temperature at the exit of a 15-ft long

tube if the tube wall condition is one of uniform heat flux of

500 Btu/hr ft2
