A$2.$a The hot and cold composite curves of a process at a pre$-$set $T_{\text{m}\text{i}\text{n}}$ are given on a $T-Q$ graph below. Determine from the graph:

i$)$ Pinch point temperature

ii$)$ Value of $T_{\text{m}\text{i}\text{n}}$

iii$)$ Is the process endothermic or exothermic?

iv$)$ Energy target

v$)$ Total amount of heat that needs to be transferred by heat exchangers

vi$)$ If $T_{\text{m}\text{i}\text{n}}$ of the process has to be increased to a value that results in an increase of hot utility usage by $90KW$ while avoiding the heat flow through the pinch, what will he the new enercy tarret valuec?
