Use the Pressure$-$Enthalpy chart to find the enthalpy of the final state point $($h$2$s$)$ of an

isentropic compression. Do this by drawing an entropy line passing over the initial state point

$($TR$1,$ PLow$\_$ABS$)$ to cut the pressure line at PHigh$\_$ABS. Read the value of specific enthalpy $($h$2$s$).$
