Is this considered a "forced air inlet"?

[Yikes]

My mechanical engineer wants to have apartments provided with an outside air intake with a powered fan. Is this what the mechanical code calls a "forced air inlet"? He's currently showing it less than 10' away from the range hood exhaust termination, which is on the underside of the balcony above.

CMC 502.2.1 Environmental Air Ducts​

Environmental air duct exhaust shall terminate not less than 3 feet (914 mm) from a property line, 10 feet (3048 mm) from a forced air inlet, 10 feet (3048 mm) above a public walkway, and 3 feet (914 mm) from openings into the building.​

You are on the right track. A forced air inlet is mechanically drawn in, not by gravity or convection .

I would say yes, absolutely. They need to be at least 10' apart.

Yes. That is basically the definition of a forced air inlet.
