Oh, sorry. It's quite hard to translate from German to English, and the original wording is just as confusing. At one point I just used google translate, because I got a bit lazy. Anyways, I'll reword the problem, without using Google Translate this time. I hope it will be a bit easier to...

Ah...sorry. I just read the problem again, μ is the mass of milk/coffee. M is probably their mass combined (?) I have a problem with a coffee machine that has two coaxial tubes. A tube has a length of 5 cm. It says that the milk flows through the space between the two tubes and the coffee...

Well...I don't know what is m, t, and μ. They only gave us this formula and didn't say anything else. That's why I'm confused. I think m is mass, though. Edit: And t is probably time, since θ was used for temperature in the problem

I don't understand how this equation came about and what μ means. And from there they said that μ=Δm/Δt=constant I have to use it to solve a problem about finding the final temperature of two liquids. I tried to google the equation, but I couldn't find anything. Can someone please explain this...
