Notes:
Heat transfer was measured for water flowing parallel to 5/8-in. rods in a triangular lattice (0.914-in. spacing). Velocity was varied from 5 to 20 ft./sec., temperature from 150° to 325°F., and heat flux from 50,000 to 200,000 B.t.u./(hr.)(sq. ft.). Reynolds numbers ranged from 70,000 to 700,000. Coefficients were 40% higher than predicted from the Colburn equation for flow in pipes by use of the equivalent diameter. The effect of heated length was studied. No variation in local coefficient around the rod periphery was found. Pressure drops were 65% higher than predicted by the Fanning equation (by use of De).
