Hello,
Can I use the pressure reading, from a pressure gauge connected to a biogas pipe (of known diameter) to calculate the flow rate of the gas flowing into a burner? The pressure gauge will be placed just after the valve to monitor the pressure flowing into a burner.
I have seen on some resources that the use of Hagen-Poiseluisse equation but I am not sure if this is accurate since this considers length of the pipe. What if the pressure gauge I am using is very close to the exit of the pipe?
Regards
Andreas
