a) A new design of water network has been proposed with the requirement of freshwater and wastewater to be treated is 106 t/h and 71 t/h, respectively. Your task is to analyze whether this value is reasonable or not. Based on data for water demands and sources of activities in Table 1, show details of the calculation on the freshwater needed and wastewater to be treated using water pinch design technique.
