This shows that n depends only upon T and T i e independent of working substance For 100 efficiency T must be OK i e the temperature of the sink must be at absolute zero Since this is impossible attaining 100 efficiency is impossible When T T we have n 0 i e the engine does not work Example 11 Calculate the efficiency of an engine that absorbs heat at 600K and exhausts it at 400K Solution T 600K T 400K Efficiency T T 600 400 600 n T n 26 6 11 13 X 08
