No titration page and calculator

[Tony]

Edit: Topic split for discussion

You could hive out part of the titration calculator and use it for a "No titration" page.

That's a good plan - might need some help with it though, I tried no-tit once but it was more hassle than titration for me.  So not completely familiar with it.

I'm in the same boat, so not much help I'm afraid ... I'm sure Vince will jump in if he reads this post.

[K.H]

Im not doing it either

OK, added no-titration calculator to the menu bar, following the advice on the wiki page for how to do it.  I'll ask Vince to check it out.

Vince says he thinks the option to put in a %age methanol should be removed and first stage should be 3.5g base for NaOH and 5g base for KOH to encourage less of a reaction in that first stage.

I've asked for base amounts to use for second stage (IE after measuring dropout).

This doesn't currently tally with the wiki page on how to do it so I think we'll have to update that when the calculator is figured out.

sorry i ment % purity caustic

i use 3.5 base stage 1 naoh & 5 base for stage 2, & 4.5 base stage 1 koh and 7 for stage 2.

other do other things so it may be best not to default to a g/l and let people put in what they want.

[Tony]

Ah gotcha.

The purity bit was because it was adapted from the titration calculator.

What I'll do is put in an entry box for second stage base amount and reduce the defaults for first stage base accordingly.   And remove the purity options, keep it simple.

[Tony]

Are we happy with an assumed purity of 99% for NaOH and 90% for KOH?

I've rewritten the no-titration calculator - how does it look now Vince?

i really don't think the purity has any need to be involved at all, we use a figure for stage one and another figure for stage 2, its done on a try and see basis and the next batch is changed slightly according to how the last batch went.

if we give accurate figures to people we will just get told it don't work, when what they should be doing is learning what works for them and understanding the process for them selves not just blindly following a list done by others.

[Tony]

Sounds reasonable.  I suppose the trouble is I like to quantify things 

For the purpose of the calculations then, should it ignore purity and assume 100% for both, leaving the rest up to the brewer's experience to tweek?  It would certainly make the calculations a bit simpler.

If nothing else it gives a double check to make sure people's workings aren't far out, when brewing a batch.

[hifly]

the problem is its not an exact science and every ones oil is differant,

i think we should just supply then empty boxes for base amounts and let them put what they want in them.

i see the calculator as just something to save getting a pen and paper out.

I have just printed out a spreadsheet with stage 2 qty per 0.1ml of drop out.

[hifly]

in fact i am not sure we even need a koh/naoh button at all

[Tony]

I see what you mean.  Don't specify the catalyst, user chooses the base, everything falls out of that.

I'll get right on it!

[Tony]

OK, how about now?
