Thank you for your reply and now I know I need to explain what I'm doing a little more. I'm trying to measure air flow through a variable orifice that is made of a spring material. Attached is a rough drawing of the device. Air flow enters the device at point A and pushes against the metal...

I'm trying to find the dynamic pressure of an airflow at 60 LPM. I'm trying to calculate the air pressure on the inlet side of a variable orifice. The variable orifice is a diaphragm loaded by a coiled spring. As the diaphragm opens, the air vents out to atmosphere through a square slot at a...

I have a basic airflow question and my mind is in the fog. I'm trying to find the air pressure at a known flow rate and orifice size but I'm having issues with the unit conversions. I'm using Bernoulli's equation Pressure = 1/2 x Air Density x Flow Rate/Area. My Flow Rate is in L/M and the area...
