Popis:	There are shown considerable discrepancies among existing diagrams, tables and empirical equations concerning pressure loss coefficient, Euler number, for tube banks of ten or more rows. In the sake of practical application, simple expressions are proposed for the diagrams of typical in-line and staggered tube arrangement in Heat exchanger Design Handbook in the range 10 ≤ Re ≤ 2 × 105 ∼106 within an accuracy of ±3%. Procedure of the formulation and an interpolation technique for applying to the cases of the other tube arrangement, namely the other pitch to diameter rations, are shown by using some examples. Also in proposed a new method of correlation for experimental data on tube banks with small number of rows.
