Question

Air, as an ideal gas flows
through the turbine and heat
exchanger arrangement shown
here. Steadystate data is
presented on the figure. Heat
losses and kinetic and potential
energy are neglected. Determine
(a) the temperature T3 in K; (b)
the power output of the second
turbine, in kW; (c) the rates of
entropy production in kW/K for
the turbines and heat exchanger;
and (d) using the results you
obtained in part (c) rank the
engineering devices starting with
the one contributing the most to inefficient operation of the overall system.
