Unformatted text preview: : 180C (we will presume that T 10 is not disturbed from this value) (outputs) T 6r : 129.3C T 8r : 223.4C T 9r : 168.8C Step (3) constitutes your design, in which the result will be heat exchanger sizes and the bypass fraction to achieve the specified outputs, for the specified inputs. Are these enough specifications to determine a unique design? Recall that the original network used three exchangers of area 117 m 2 ; any or all of these may change for the new designs. Furthermore, the manipulated variables may assume new reference values. revised 2004 Nov 30 Dr. Barry S. Johnston, Copyright 2004. 1...
