Answer Posted / engr. nahid
Impurities are having a special properties of good
conductivity. When small amount of impurities added in
semiconductor type material, this conductivity is then
counted as the whole semiconductors conductivity. Thus
increasing conductivity of the semiconductor. Usually a
small amount 0.1% to 1% impurities a enough to get proper
conductivity of the material on which this need to increased.

In Rankine Cycle we use the concept of Tm(mean temperature of heat addition).In actual cycle the efficiency comes as n=1-T2/T1 Taking Tm into consideration it comes as n=1-T2/Tm as T1>Tm so the efficiency for both case will not same for a same cycle. Can anybody explain how it is possible? Advance appreciation for your effort.Thanks
