1) [15] Perform a heat exchange network analysis** (4 of the first 5 steps) on a set of 5 streams where streams 1-2 are cooling and streams 3-4 are heating. Make sure the minimum utility requirement is met. cold Stream 1 2. 3 4 mdotcp (kJ/K) 2 3 4 2 Tin (C) 250 240 130 190 Tout (C) 120 140 230 240 Your answer should include a temperature interval diagram, cascade diagram, and diagram showing the minimum number of exchangers. You do not need to show the heat exchanger network. Make sure to point out the pinch temperature, net heat transfer, Qc, and Qn. You can use a minimum approach temperature of 10C
