Ladies And Gentlemen
I am looking for the equation for measurement of air flow under pressure 600 mm Hg to 300 mm Hg through 4 mm diameter port. In the same time, I am looking for supply of test benches for the same purpose. Screw or centrifugal vacuum pumps are preferable.
I look forward to your kind response.
With kindest regards.
Yours sincerely,
