QUESTIONS: 1. The temperature interval diagram for a process is shown below. For this process, do the following: Stream 1 2 3 4 5 6 HCFR (kW/C) 1.0 ? 3.0 5.0 ? 4.0 EHCFR AT (kW) 1 600 (C) 580 (C) 400 D A 500 (C) 480 (C) B ? 2 3 400 (C) 380 (C) 4 -600 300 (C) 280 (C) D 300 200 (C) 180 (C) 5 E ? 100(C) 80 (C) 6 a. Compute the missing values of HCFR for Streams 2 and 5 and the missing Q values for temperature intervals B and E. b. Calculate the minimum hot and cold utility loads for this process subject to a minimum approach temperature 20 (C). c. Calculate the pinch temperatures for this process. Assume that there is only one hot and one cold utility available
