Kind of, except for the units. Sanity check: does it make sense for a flow of this type which is perhaps a carburetor venturi or a wind tunnel flow, to be going only 300 feet in an entire minute? A regional pilot can run more than 500 ft per minute which is of course seriously slow by human standards
, so this air would be going a lot faster; how about V2= 300 ft/sec. You can treat this problem as a two dimensional flow.
