Frage zu Wasserverhältnis?
Goede Dag
Meine Frage: Will jetzt Wasserkochen im WK und in eine Thermos geben die circa 1,2L fasst. Der Thermos fasst 1,2L. Will auf den fertigen, sehr heißen Tee im Thermos, kaltes Wasser geben.
Stellt sich jetzt die Frage was für ein Prozentverhältnis es ungefähr sein soll.
Ich mache jetzt die Thermos zu wie viel Prozent mit kochendem Wasser voll? 50? 70? 80 Prozent? Den Rest fülle ich wie gesagt nach dem der Tee gezogen hat mit kaltem Wasser auf.

That’s a question about mixing. For the sake of simplicity, we assume that the heat capacity of water does not have a temperature gradient.
Do you know the “Andreaskreuz” in the mix calculation? You need three details: temperature hot water, temperature cold water and desired temperature (between).
Determine the differences (hot minus desire) and the difference (hot minus cold).
Now take as many parts as hot as (Wunsch minus cold) and from the cold call as many parts as (hot minus desire). Then you should get close to the wish. With some experience, you can still balance the heat capacity of the thermoscan by flushing it out hot beforehand.
First prepare the tea only with hot water and tea powder for the total volume and dilute/cool it shortly before drinking. You’ll get it.
It depends on what temperature it has after pulling, and what temperature you would like to dilute after that.
When calculating with the mixing cross, you should consider that cooling. Fresh water from the clear line can be charged at 8°C.
