AI Thread Summary
The discussion focuses on rearranging the equation X=Y-0.0065*Z*Y^.6 to solve for Y. Participants express skepticism about the feasibility of isolating Y in this equation. The equation originates from empirical research related to the lift coefficient of a boat's planing surface from the 1960s. The user has attempted to plot the equation in Excel and derive a trendline for better fitting, although this process is described as cumbersome. The conversation highlights the challenges of manipulating complex equations in practical applications.

I don't think you can …

wherever does an equation like that come from? :smile:
 
Thanks for the welcome. The equation comes from emperical equations from a tow tank in the 1960's to define the lift coefficient of a deadrise planing surface of a boat at speed. Thanks for the help. I have plotted the equation in excel then added a trendline to get a good fit and backed out equations, very cumbersome.
