Hybrid Fueling Spreadsheet

Unread postAuthor: saefroch » Sat Jan 29, 2011 7:50 pm

I believe it was suggested earlier that somebody create a spreadsheet for hybrid fueling, so because I had about half an hour after the AP chem midterm and I was in a rather chemistry-ish mood I wrote out the formulas and produced a spreadsheet when I got home. I think it works, but I can't be totally sure. I'll probably use the spreadsheet to do calculations for my upcoming (eventually :roll:) hybrid.

Can anyone check my results?

Don't mean to rush, but any feedback yet? Anyone else feel like checking my numbers? Not exactly a cheery task, but I'd like to know if I screwed up real bad or not...

Its not a very appealing task in the first place, so not many people would go to the trouble as to ask for it. Why don't you just post it? Everyone makes mistakes, no one's going to belittle you for failures, unless of course you have an exploding/farting/whizzing epoxy prototype :lol:

I saw that :P

What does the spreadsheet do?

Do you input fuel type, chamber volume and mix number and it gives you volume/psi of fuel to be injected?

I used my telepathic powers to read your mind and determine that your calculations are indeed correct.

Congratulations.

Okay, well it was originally implied that I could e-mail the spreadsheet to members wishing to see it :roll: but that now seems to me to be stupid.

Tell me how to upload a downloadable file, and you'll see.

I saw that, but there's no spreadsheet options.

This should work though.

EDIT: Put the link in the original post as well.

*facepalm* there are zip/rar options!

Anyway, looks good, though I would have included a column with the volume of fuel necessary at atmospheric pressure for us syringe fuelling types ;)

Add the excel sheet to the spudwiki when you think it is done.

Maybe to
http://www.spudfiles.com/spud_wiki/inde ... lculations
or to the hybrid page
