1.	Find the theoretical maximum efficiency of a steam engine using an intake steam temperature of 100^(@)C, if it is operated in a place where the exhaust temperature is 0^(@)C. If super heated steam at 200^(@)C is used, what is the maximum possible efficiency?
Answer» Solution :`T_(1) = 100^(@)C = 373 K, T_(2) = 0^(@)C = 273 K` Efficiency `= eta = (T_(1) - T_(2))/( T_(1)) = (373 - 273)/(373)` ` = 0. 268 = 26.8%` `T_(1) = 200^(@)C = 473 K, T_(2) = 0^(@)C = 273 K` Efficiency `= eta = ( T_(1) - T_(2))/( T_(1)) = (473 - 273)/(373)= (200)/(373) = 0.536= 53.6%`
