Project Rho has a bunch about nomograms at http://www.projectrho.com/nomogram/index.html .

One example, at http://www.projectrho.com/public_html/rocket/engines.php#nom... , is a Delta-V Nomogram for the solar system. Given your exhaust velocity and mass-fraction you can compute your delta-V, and combinations thereof.

The last time I saw a physical one (ie, "in real life") was on a booklet for parents of newborns. It estimated the child's predicted height based on the heights of the parents.
