Hi,
In the GPSA book, there's a section regarding the gas orifice calculations in Example 3-1.
It happens that the related equation is :
Qh = Keyg Ftf Fg (hwPf)^0.5
I understand that Ftf is the flowing temperature factor to change from the assumed flowing temperature of 15'C to the actual flowing temperature, but i couldn't figure out how to get the Ftf value.
Can anyone enlighten me on this?
Thank you.
