    Answer:

    The value is \eta = 63\%

    Explanation:

    Generally the thermal efficiency is mathematically represented as

    \eta =  1 -  \frac{T_L}{T_H} * 100

    substituting  [ 627°C + 273  =  900K ]  for   T_H and    [ 90°C + 273  =  333K ]  for  T_L

       So  

             \eta =  1 -  \frac{333}{900} *100

    =>     \eta = 63\%
