question on air flow rate
question on air flow rate
(OP)
If an air tank is filled with 150 psi air. If I want the release the air at a certain rate, say, 20 ml/sec. Is that determined by the size of the orifice? So by varying the size of the orifice with a valve, I can control the air release rate right? If so, can someone tell me the math formula for it?
Thanks
Thanks

However, as Katmar has pointed out, the flow rate will vary with input pressure for any fixed needle valve position.
However, if your tank pressure is replenished on a periodic basis, for instance, like an iar compressor tank, then install a pressure regulator upstream of the flow regulator.
The regulator brings the tank pressure down from 150 psi to a lower pressure, say 20 psi, which can support your flow rate, and still be high enough to be replenished by the assumed air compressor, before the tank is exhausted.

Mass produced, does anyone know about much cost the added regulator would add?
