Theory and Design of Axial Flow Fan (Part III)
Transactions of the Japan Society of Mechanical Engineers, 1953 The condition that the axial flow fan is to be operated at maximum efficiency is to make the overall manometric efficiency maximum taking also the loss of pipe line which is connected the fan into consideration. We show a disign to obtain the maximum manometric efficiency, in two cases where the diameter of impeller is determined freely or given, when ...
