Cylinder Head Flow Conversion

[Ohio HD]

I was reading an article regarding head flow in this quarters Engine Professional, within the article was a flow rate conversion chart. Handy for comparing flow results from different vendors that are using different pressures to test at.

It's attached below.

Why not just use the formula?  Tables and slide rules are the things of the past..

Max, why not use the chart? It is a formula, a x b = c is a formula.

But just for you.....

flow pressure messured at 10" = 170
flow pressure desired at 28" = 284.5

√(28/10)*170=284.5
