2. A process stream is cooled from 45°C to 20°C in a shell-and-tube heat exchanger using refrigerated water (RW) in the tube side that enters the cooler at 5°C and

leaves at 15°C under nominal condition. Under nominal condition, there are equal resistances to heat transfer on shell and tube sides. The process stream and RW flow-rates through the cooler are increased by 33% and 20% with respect to their nominal values, respectively. What would be the outlet temperatures of the process stream and RW?2.5+2.5
