Q4A lydrocarbon liquid from a fractionation tower is to be cooled by air in an air cooler from 225 F to 130 F. The flow rate of the hydrocarbon fluid, is 320000Lb/hr. The ambient air is at 95 1. The tubes of the air cooler has 2 rows) and two passes each tube is 1 inch outside diameter 16 BWG using 5/8 inch leigh fins, 10 fins /incl. The air cooler length is 30 ft. with two fans and using: 2.5 inch triangular pitch. The viscosity is 1 ep and specific leat is 0.6 for the hydrocarbon liquid, and 0.24 BTUIDF for air.
