A certain solar energy collector produces a maximum temperature of 100°C. The energy is used in a cyclic heat engine that operat
Gwar [14]

Answer:

\eta _{max} = 0.2413 = 24.13%

\eta' _{max} = 0.5061 = 50.61%

Given:

T_{1max} = 100^{\circ} = 273 + 100 = 373 K

operating temperature of heat engine, T_{2} = 10^{\circ} = 273 + 10 = 283 K

T_{3max} = 300^{\circ} = 273 + 300 = 573 K

Solution:

For a  reversible cycle, maximum efficiency, \eta _{max} is given by:

\eta _{max} = 1 - \frac{T_{2}}{T_{1max}}

\eta _{max} = 1 - \frac{283}{373} = 0.24

\eta _{max} = 0.2413 = 24.13%

Now, on re designing collector, maximum temperature, T_{3max} changes to 300^{\circ}, so, the new maximum efficiency,  \eta' _{max} is given by:

\eta' _{max} = 1 - \frac{T_{2}}{T_{3max}}

\eta _{max} = 1 - \frac{283}{573} = 0.5061

\eta _{max} = 0.5061 = 50.61%
