Every 1 minute, 3L of water gets heated by 50K. With a specific heat capacity of 4200 J / kg / C and density of 1 g / mL, it takes 3 x 4200 x 50 = 630000J per minute.
With a rate of 4.0 x 10^4 J / g for the heater, we can get the rate of combustion with 630000 / 40000 = 15.75 g per minute.
- Thanks for doing my homework
  
  No problem

Kanye is a literal admitted Nazi.
Stop dickriding this fucking loser or using him in memes like he's just some dude. Stop being complicit in normalizing Nazism, Jesus fucking Christ
- It could be funny if not for this guy's rapidly stagnating mental health and the publicity he still has. He's not a joke, he's a deeply wrong unmedicated idiot who we can observe even there. When he was intervieved with a sock on his sad head and praised Hitler for some reason, it felt so cringe-worthy, but it's unfair to him and to the persons who he promotes hate against to share it any further.
  
  Mental illness isn't carte blanche to be hateful without recourse. I live with literally the exact same condition as Kanye, but that condition never absolves me the work of being decent or having to live with the consequences of my poor decisions. My mental illness may at times explain my erratic behavior, but it absolutely never excuses said behavior. Stop using mental illness as an excuse to allow the rich and famous to do whatever they want without recourse.
  
  I recall he had a ski mask on his head, the sock was on his hand
- Just because the guy in memes is a jerk doesnt mean we cant laugh at memes.
  There are literal Hitler memes on the internet.
  Do you think people who put Satan in their memes want to really go to hell or something?
  
  Of course I understand that, but I also understand subtext and cultural currents. Regardless of whether or not using Kanye this way counts as endorsement, it still serves to normalize his relevance and help keep him, and therefore his thoughts, words, and opinions, in the cultural zeitgeist.
  So we can either accept that or choose literally any other random idiot to be our go-to meme guy instead.
  So why the fuck shouldn't we?

You have 3 liters of water heating up by 50 degrees celsius. It takes 4184 joules to heat 1 liter of liquid water by one degree Celsius, so it takes 627600 joules to heat 3 liters by 50 degrees. Dividing by 40000 joules per gram of fuel, it will take 15.69 grams of fuel per minute. Finally, for significant digits, we have to round to 16. grams of fuel per minute.
Edit: for most sciency uses, 1.6 times 10^1 grams of fuel per minute is likely the preferred way to write that.
- Who are ye, so wise in the ways of Thermodynamics
  
  Ye are rapper
  
  Probably a witch, and we would normally burn them...but burning a witch who is wise in the ways of Thermodynamics is like shooting marsh water at a swamp monster.
- Its going from 7 to 77, not 57
  
  Its going from 7 to 77, not 57
  "from 2 7°C to 77°C" is either "from 27°C to 77°C" with an extremely problematic line break position, or something unintelligible.
  
  Oh I missed that 2 7, thought it was Delta 70 as well on first glance.
- Hey, just curious... when you say that it takes a specific amount of joules to heat water, why is the time variable, surface area of the body of water and surrounding temperature ignored? It seems so weird to me to hear that it takes a fixed amount of energy to heat water from temperature A to temperature B. I feel there are so many more variables involved.
  Are you just ignoring variables for the sake of being able to give an answer? Seems to me like a classic scenario of "they taught me to ignore these variables in physics class". Or am I wrong? I'm very curious. I was trying to solve it logically but it wasn't possible due to missing variables. I have no clue about thermodynamics.
  
  I'm ignoring many factors for the sake of being able to answer. There are some kinds of heating, especially using burning fuels that are nearly 100% efficient, but we don't know why it needs to get to that temperature, or how long it needs to stay that hot - so even if the transfer of heat is 100% efficient, this computation may underestimate the actual needs.
