This paper shows analysis of experimental results of the total pressure drop and heat exchange in flow across banks of tubes. Two different bank types were taken into consideration: plain tubes and fined tubes. In this paper author suggests an exponential form of the relation Eu=f(Re). Spatial distributions of the heat transfer coefficient on the outer surface of plain and fined tubes are also determined.
