I have a problem. Why does Gy or J appear near tonne?


NH.3_ex_c_r:NH.3_ex_c*M.ex_c=1227.6454 Gy tonne


NH.3_ex_c_r:NH.3_ex_c*M.ex_c=1.2276*10^6 J tonne

Hi Adis,

We'll need more information to help you. could you please post the .sm file you're referencing?

"tonne" reminds me a Mathcad bug in the German version.
It also appeared in the Mathsoft "Fourier model" English US version.

In your file I can't find neither NH.3_ex_c nor M.ex_c

Real result is 1.2276 tone. 1 tone = 1000 kg

I think i fixed the issue. See attached.

I have disabled some of your manual unit definition and performed some cleanup.

Generally you do not want to overwrite units already defined within Smath and you were re-defining already defined units.

The issue, I believe came with your definition of H.ii_c. You applied units to the result and toggled ignore units. This made it seem like the result evaluated to kJ/kg when in fact it was unitless.

This propagated through to the result in question.

Above my head ! why do we still have tonne ?
For God sake what's that in Smath ?
What was it in Mathcad ?

What is the difference between "Titration and MassBalance" ?

In case of interest, PseudoInverse works fine in Smath.

1 tonne is defined as 1000 kg. Same thing as a Mg.

Thnks alyless,

ton(short)

short is t

Thank you very much! The original file was worked in Mathcad. After conversion to SMath Studio, some errors occurred. In the future, I will only use the defined units.

Oh !, you are the man of science in there.
I know about titration from past professional [Process Control & Instrumentation]
Not so easy ... so and so ... generally Ph control.
Did you visit PseudoMatrix ? Any use for your project ?
