What do you mean by a "cross flow" fan?

Do you mean a centrifugal fan with non-axial flow?

RE: cross flow fan

There is really no formula for fan sizes.

There are many fan blade types (radial, backward inclined, forward curved, axial and etc) depending upon the use for the fan.

There are probably some theoretical formulas for fan air flow.   However the fan manufacturer's literature is the place to start. You need to know how much air you want to move and what static pressure rise the fan is required to develope.
