(HgAh)=ChG^mL^n
(HdAm)=CmG^pL^q


I need to plot (HgAh) and (HdAm) As Fuction of G( Gas flow rate) with lines of Constant L( Liquid flow rate) and discern M and P from the equations above from Log Log Graphs.

I have collected a table of raw data with Various G at constant L.

How do I proceed?

It depends on the software you have available.
I can recommend gnuplot. It's free, it's good, and it's a standard tool.

Can't I just do it on excel ?
I don't undersntand how to get P and M from these equations by taking the log

log (hG aH) = log (Ch G^m L^n)

and

log ( hD aM) = log (Cm G^p L^q)

any idea?
 
I already have all the HdAm and HgAh for various Gas and Liquid flowrates
