The two critical variables for flow rate will be resistance and diameter/area of flow. The holes in the outer zones could be over drilled to increase their diameters. If that is not an option then reducing the number of holes in the central zone and increasing the number of holes in the out zone would help. Alternatively, as others have stated, you could ...

you could add a diverter fin like a n inverse V inside to give favore to the side openins and deny direct suction from center openings. as per my sketch.

I would suggest separate channels to each set of holes with orifice plates to limit the flow to / from each. That way you can control each set individually. The other solution will be to over-specify the flow rate so that the poorest one is sufficient...

It will be a next to impossible task to try and analytically predict the number/position/size of the holes in order to have exactly the same flow. Even if you do for a temperature and a set humidity, at different temperatures you might have unacceptable results. If you are really interested in equalising the flows, a better alternative is to use a flow ...

Goosenecks use either a series of friction joints or some sort of wire member that will hold its shape when bent. If a vertical force is applied to the screen in your picture then maximum torque will occur at the furthest point from the screen and it will flex there. I'm looking for the curvature that will offer greatest mobility and stability, while also ...

The simplest answer to the question is "because the motorcycle gets in its own way" Take a look at this picture of a trials motorcycle; it has perhaps the smallest of turning circles available in a motorcycle of a given length: And here's a picture of a typical bicycle steering/suspension setup: On a motorcycle, it's fairly universal to have the ...

I'll approach this from a different perspective to the other answers: Pushbikes have no limits on the steering range because they don't need to add the complexity and weight. They're simple, light, and traditional, so include only the features necessary. Turning the bars more than a few degrees while riding along at any decent speed isn't needed, bu it may ...

A bicycle usually weights about 18 pounds versus an average of 180 pounds for a motorcycle. In tight turns a bicycle can easily be controlled by the rider shifting their body's center of mass as needed to nudge the bicycle to turn or correct extra overturning moments, by leaning in or out of the turn while playing with the handle bar. The weight of front ...

Although there is a correlation between high speed, stability and limited steering range, I think this question is about low velocities. I.e. why even for low velocities, there is still not enough steering range for motorcycles. Therefore, IMHO, the reasoning that at high velocities need larger radii does not by itself prohibit greater steering range at ...
