A process stream is cooled from 45C to 20C in a shell-and-tube heat exchanger using refrigerated water (RW) in the tube side that enters the cooler at 5C and leaves at 15C under nominal condition. Under nominal condition, there are equal resistances to heat transfer on shell and tube sides. The process stream and RW flowrates through the cooler are increased by 33% and 20% of their nominal values, respectively.  What would be the outlet temperatures of the process stream and RW?
