From compressor , the air will be stored in a tank from where it will be taken out through 40mm tube. constant flow rate can be maintained?

Edit 1:
From the compressor me is storing lets say 1 cubic meter of air in a tank.
The tank  has its inlet and outlet, from the outlet, air is taken out for application so there would a volume reduction in storage tank.

so how we can manage that air reduction in the tank?( me need to maintain a constant flow-rate at outlet and from the compressor me can able to store the air to the tank, but how??

at what pressure i need to know the practical and theoretical stuffs

Using compressor we can manage air flow rate know. Please be precise with your question

Have you tried some methods ?
i am trying,once done will let u know

Selected Ans.

The condition for flow to be constant is to have the pressure constant.

but since it is a storage tank, that might not be possible. if the tank has an input feed from the compressor and the delivery flow matches the inlet flow for a given period of time. then the ripples in the pressure can be filtered out with the storage tank and the pressure and flow will be more or less constant.

If the output flow stops a pressure sensor can trip the input compressor feed to the storage tank to keep the pressure constant.

If the flow required is greater that that what the compressor can deliver, the system would be unstable and would stabilize at the flow rate the compressor can deliver.

If the flow from the compressor is much higher than what is required at the delivery, then the compressor could be tripped intermittently to maintain pressure within set points to ensure the flow is constant (pressure controlled).

Or use a VFD (variable frequency drive) to operate the compressor motor at the flow required.

Thanks for answer... i am also trying in that way , ,,,, compressor needs triggered on when flow rate falls below the requirement. i have to see the practical variations
