    Physics and Beer, the perfect union

    Thanks guys, you've been a lot of help.

    Thanks, that works great. The reason it comes out to be 70 degress C is because that's what tempt it comes out of the mash at. For starches to be converted to sugars the grains must be heated in a sticky mash between 150F and 160F for about an hour. The grain husks then becomes a filtering...

    additionally, how much further should i get to get a violent boil rather then a simmering boil. Is there any way to quantify that? To effectively get ride of certain undesirables in beer (the reason why budweiser smells like cooked corn), one needs to give a vigorous boil.

    wait! I just figured out what I did wrong. 0.4536 kilogram by 5/9 a degree C (NOT 9/5 A DEGREE) or rather 1 kg by .252 degrees C or even 3.968 joule should raise 1 kg of water by 1 degree C That should give me 2380 seconds or 39.6 minutes. Am I doing it right now? How do I get a...

    Physics and Beer, the perfect union

    i guess i was looking more for some sort of explanation as to how those numbers above were derived so i can plug in different factors and see what's acceptable. I'd obviously like the least amount of time possible but it's going to have to be weighed against more practical things like the...

    hmm, probably not quick enough for my purposes. What are the assumptions you made to get that answer so I can plug it in for different scenarios? Any simple equations would help. Do I really only get 65% efficiency on something like that? What else is it being translated into if it's not...

    haha, great idea but the problem is that i can't fit the pot on my stove. When i did that at my last place i scorched teh stove and counter and my girlfriend had my head. I want to be able to do it all in the living room on a ceramic plate. Thanks for the tip though.

    Physics and Beer, the perfect union

    I brew beer as a hobby and in order to avoid the cold i want to take my boiling inside. Because propane inside my apartment is dangerous I was looking to heat my boil with a modified electric heating element from a hot water heater. I need to figure out an equation that will tell me how...
