my.che.utah.edu• If the tower is higher than 190 ft, then a design with smaller tray spacing should be considered (Douglas, 1988). The tower height can be related to the number of trays in the column. The following formula assumes that a spacing of two feet between trays will be sufficient including additional five to ten feet at both ends of the tower.
