(25 pts.) Two reversible Carnot engines operate in series. The first engine absorbs heat from a reservoir at TH=1600K and rejects heat to a reservoir at temperature T. The second engine absorbs the amount of heat rejected by the first engine at T and rejects heat to a reservoir at TL=400K. Calculate the temperature T for the case for which:
(a) the thermal efficiencies of both engines are equal.
(b) both engines produce the same work output.
