Problem $\backslash$#$1-$ For the system described in the schematic below, determine the combined power requirements $($in kW $)$ and the mass flow at states $1$ and $3.$ The system operates with a high$-$temperature evaporator at $\backslash (20^\{\backslash$circ$\}\backslash$mathrm$\{$F$\}\backslash )($and $100$ tons of refrigeration$)$ and a low$-$temperature evaporator at $\backslash (-20^\{\backslash$circ$\}\backslash$mathrm$\{$F$\}\backslash )($and $150$ tons of refrigeration$).$ The condensing temperature is $\backslash (100^\{\backslash$circ$\}\backslash$mathrm$\{$F$\}\backslash ).$ Show all work.
