An ion-exchange process using a resin to remove copper ions from an aqueous solution is conducted in a 1.0-in.-diameter column 1.2 ft high. the flow rate is 1.5 gph and the break point occurred at 7.0 min. integrating the breakthrough curve gives a ratio of usable capacity to total capacity of 0.60. design a new tower that will be 3.0 ft high and operate at 4.5 gph. calculate the new tower size and break-point time. ans. tb
