A well insulated gas turbine of a technical power of $110$ kW uses air $(0\mathrm{.}5$kg$/$s$)$ as working

fluid at a pressure of p$1=10$ bar and a temperature of $573$ K expanded to atmospheric

pressure. Calculate the exergetic loss of the process for an ambient temperature of tamb $=$

$20$C$.$ Calculate the entropy produced first$2$
