FIG. 10 CORRELATION OF PRESSURE-DROP FACTOR / INDEPENDENT OF REYNOLDS NUMBER Discussion DAVID DROPKIN. 6 The authors have made a valuable contribution to this important field of heat transfer and are to be commended on the scope and clarity of their paper. There is, however, some additional information that is pertinent to this report. In Fig. 2 , for the ST/D X SL/D arrangements of 2 X l'A and 2X2, the pressure-drop factor/shows a rapid rise at the higher Rejmolds numbers. For example, in the

... X2 arrangement / increases from about 0.26 to 0.42 in the range of Reynolds number from about 25,000 to 32,000.
