$5\mathrm{.}12$ Exergetic losses of small gas turbine

A well insulated gas turbine of a technical power of $110kW$ uses air $(0\mathrm{.}5k\frac{g}{s})$ as working fluid at a

pressure of $p_1=10$ bar and a temperature of $573K$ expanded to atmospheric pressure. Calculate the

exergetic loss of the process for an ambient temperature of $t_{\text{a}\text{m}\text{b}}=20C.$ Calculate the entropy produced

first ${?}^6.$
