There is no set size. The size depends on how many Btu of heat is needed for the burner in the appliance , heater or machine you are running .
Orifice size corrected to reference temperature.
It is best to contact the appliance manufacturer for correct orifice size when converting from one type of gas to another.
If u magnified the cell as 30000 times then the length you measure(3.5mm)is 30000 times the actual length so divide 3.5 by 30000 to get your answer

The calibration curve for an orifice meter will depend on the size of the orifice, the size of the pipe and the pressure loss over the meter. Typical calibration curves have pressure (or head) loss on the vertical (y) axis and flow rate on the horizontal (x) axis.
accoring to the size.
30000 and through the war 30000
change the gas flow metering orifice size
surgical incision or digital disruption of the components of a commissure to increase the size of the orifice.
You have to change the size of the gas suypply orifice.
A/C Orifice Tubes. The orifice tube acts as a small filter and restrictor inside the a/c system. The Freon gas passes through the small screen mesh of the tube and any debris (mostly metal shavings that come from normal wear and tear of the compressor) will get trapped, and the Freon gas will also be slowed down and restricted as it passes through the small opening of the orifice. There are different orifice tubes with different size openings/restrictions, and the color of the orifice can differentiate their diameter
