Henssge nomogram

Henssge nomogram

We weren't concerned with usage of nomogram in practice or correlation of measurements and reality. We present here a numeric solution of equation, with usage of PC and MS Excel. We used Newton's method with more complicated founding of zero approximation to get the solution.

There was written a lot about this problem; we based our calculation on these equations: below 23°C and above 23°C (we don't know the author or the source).

An article about usage of nomogram was published in Kriminalistika 1/2005
