Calculate the ideal Carnot efficiency of a steam turbine that utilizes steam at $$\text { a temperature of } 575 ^ { \circ } \mathrm { C } \text { and ejects water to the environment at a temperature of } 35 ^ { \circ } \mathrm { C } \text {. }$$

Question

Quizplus · Accepted Answer

The Answer is Converting temperatures to Kelvin gives

T _ { h } = 575 + 273 = 848 \mathrm {~K}

and

T _ { C } = 35 + 273 = 308 \mathrm {~K}

The ideal Carnot efficiency is given by

\eta = 100 imes \left( 1 - \frac { 308 \mathrm {~K} } { 848 \mathrm {~K} } ight) = 63.7 \%
