How to calculate the air flow (volume flow in m3/s) through an orifice of diameter ∅ 1mm, 1.2 mm and 1.5 and length 1mm? The air at room temperature is sampled through the orifice from atmosphere at pressure 1013 mbar. The pressure behind the orifice is regulated at 100 mbar or 200 mbar.
Thank you for your help

Hi, there's a nice free program that will help you calculate the flow rate. Google "Daniel orifice flow calculator". You'll need an internal pipe size to complete the calculation.

Thank you but thus program works for pipe only with inner and outer diameter included as beta coefficient.
My question concerns only nozzle (orifice) of ∅ 1mm, 1.2 mm and 1.5 mm with no outer diameter.

Flow through orifice?

You can use the Bernoulli's energy equation to solve for the flow noting that it is constant.
