WebFor pressure drop inside tubes, d is 0.046 and F is the fluid- flow path length. Across tubes banks, a is 0.75 and F is the product of the number of tube rows and the number of fluid passes across the tube bank. The physical property term is again tabulated after being normalised so that the lowest value is approximately unity. http://www.mhtl.uwaterloo.ca/pdf_papers/mhtl06-14.pdf
