And you do not give the specific structure of the valve, so there is no way to talk about the calculation. The simplest way is to install the pressure gauge and the flow meter on both ends of the valve, and read the data directly.

Q: How to check if the gas valve is open?: The valve handle and pipe as "one" word proved to come, as "ten" word is off. Another simple way is to turn clockwise and turn counterclockwise..Chasing the answerThe valve handle and pipe as "one" word proved to come, as "ten" word is off.
