Hi everyone.(adsbygoogle = window.adsbygoogle || []).push({});

So i have a simple problem and its really confusing me, although i think i might have been starring at the page too long.

I have a pipe which has 4 inlets and one outlet; via air being pulled through via a centrifugal pump. Think of the inlets as pulling air from atmosphere like in an air conditioning unit

The single outlet is 360mm diameter which is flowing at 15 m/s.

2 of the inlets are 125mm diameter

the other 2 are 150 mm diameter

Using basic continuity and mass balance is it possible to determine the flow rates?

I'm guessing it could be a simple ratio problem?

If they were all the same diameter (say 125) it would be simple as the flow would be the same at each inlet (31.1 m/s)

Please help me out, thanks.
