Certainly not window screen mesh which is for keeping out very small insects and even a degree of pollen.
The Racing Beat screens are just the right size as not to adversely affect airflow, but strong enough to protect against reasonable rock strikes. And of course the Mazda which I have on my A/C condenser.
OK, I think we've answered the OP's question and sufficiently beat this dead horse.

In a carburetor, maybe, where there is a large opening and the constriction happens gradually, allowing for laminar flow. Venturi ends where turbulence begins. For air striking a wire at right angles, there is a lot of turbulence == disordered flow, and energy is dissipated. Even a fairly large mesh can reduce airflow considerably, compared to an unobstructed opening. Small mesh size reduces flow dramatically. You'll notice most oem protection has openings of significant size.
I tend to agree, because it's more complicated than simple airflow through the mesh. The radiators already present an obstruction so there is only so much air that can pass anyway. That being said, I would not go with very small mesh sizes. Window-screen mesh, for example, seems far too restrictive. For my own screen I went with mesh with 1/2-inch openings. Flow through multiple obstructions like this is quite a complicated problem in fluid dynamics. I don't have the math for it, so I err on the side of caution

... I guess we're not done beatin'.....
My last couple were just for fun if you didn't pick up on that. This "rock strike protection" discussion doesn't really justify advanced physics and fluid dynamics, does it?

Lol, I can take care of my own fluid dynamics guys I'm an engineer I just didn't know what size the screens were and if they were really worth the time and money, but it seems they are thanks very much for all the help they'll be here Wednesday.
