    Graph Log Plot
Click For Summary
To plot the equations (HgAh) and (HdAm) as functions of gas flow rate (G) with constant liquid flow rate (L), the user needs to take the logarithm of both equations to discern the values of M and P. The recommended software for this task is gnuplot, which is a free and effective tool for creating log-log graphs. Excel can also be used for plotting, although the user expressed uncertainty about extracting M and P from the logarithmic transformations. The equations can be rewritten in logarithmic form to facilitate the analysis. The user already has the necessary data for various gas and liquid flow rates to proceed with the plotting.

(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
 

Thread 'Area of Overlapping Squares'

Here is a little puzzle from the book 100 Geometric Games by Pierre Berloquin. The side of a small square is one meter long and the side of a larger square one and a half meters long. One vertex of the large square is at the center of the small square. The side of the large square cuts two sides of the small square into one- third parts and two-thirds parts. What is the area where the squares overlap?
