The simpltfying assamptions made by Merkel ure critically evaluated by comparing the Merkel analysis to the more rigoroas Poppe analysis of cooling tower performnnce. It is shown that the uccaracy of the Merkel method can be greatly improved, under certain cooling tower operating conditions, to predict cooling tower performance within very close tolerance of the performance predicted by the Poppe method, It is shown under which tower operating conditions the thermal tower performance, according to the Merkel method, is likely to diffe, from the performance predicted by the Poppe method.
