Please estimate gas flow rate 2

[knowlittle]

I need to estimate the flow rate of methane gas. From the CH4 tank, I regulate pressure to 2-3 psi. This is fed to a bunsen burner. I further choke the flow (by turning the flow know of the burner) so that flame height is only about an inch. All tubings are 1/4" id.

I am going to buy a mass flow sensor to measure the exact flow rate. But the flow sensor comes in different flow rate ranges. I need an educated guestimate. Thank you.

Probably going to be around 5 to 15 cubic feet per hour.

This paper has some flow values in it.

If it ain't broke, don't fix it. If it's not safe ... make it that way.

You folks are awesome. Thanks.

A follow-up question. Actually, I need to measure flame temp and heat amount. For flame temp, can I use a thermocouple? For heat amount, can I assume a complete combustion of CH4? Thanks.
