Answer:
(b) 56%
Explanation:
the maximum thermal efficiency is possible only when power cycle is reversible in nature and when power cycle is reversible in nature the thermal efficiency depends on the temperature
here we have given T₁ (Higher temperature)= 600+273=873
lower temperature T₂=110+273=383
Efficiency of power cycle is given by =1-[tex]\frac{T2}{T1}[/tex]
=1-[tex]\frac{383}{873}[/tex]
=1-0.43871
=.56
=56%
