And if I call the plumber, do I empty the pool? with $ 50 I solve everything, don't you think?Math just for fun. I start with the problem and publish answer later, so you can try to solve it.
Most of the questions I will post are problems that services such as Wolfram Alpha can't understand or will offer wrong answer.
Problem 1.
Diameter of the circle shaped pool is 30m and height 3m. Water in the pool contains mercury and the concentration is 0.2µg/l. Contaminated water is pumped off 1000l/hour and it's replaced with the clean water in same rate. Let's also make an assumption that mercury is evenly mixed with the water.
a) Create a differential equation for the amount of mercury x(t) (µg) function of the t (h) and solve.
b) How long it takes to concentration of the mercury to go under 0.07µg/l?
Luckily I don't live in Finland, you are too expensive. Here with $ 50 they empty the pool and take your dog for a walkFunny thing is that in Finland they would such laugh and hang up if you would offer 50 dollars for them to come empty your pool.

These are math problems. No real life solution is needed. This is just math for fun.These days I am working on water station where several stages will clean up the water first tank from mud and inject chem to kill bacteria and other bio organism, before pumping the clean water up to the final tank.
To solve the above problem, I first shut off the pump, drain the contaminated water, clean and decontaminate the tanks and then turn on the pump again.
This is a life support process and can't leave it for equations and calculations. Residue and impurities can remain for many reasons if not cleaned.

I will publish correct answers today, so if someone still want to try to solve first question.
You had correct answer for the second part of the problem.I got an answer for part b , but no idea on the equation part
92 days 19 hours 13 minutes 36 seconds (Concentration @ 0.06999999276529222 µg/l)
That's the case always. We always are closing to some value, but never truly reach it. Everything is just approximation of something.Theoretically the contamination will always be there and never end.. Endless dilution.
Percentage will be smaller and smaller for ever, but never reaches 0.
In mathematical terms it will never get to zero. It's closing to it, but never ever reach it. Do not try to think this as an real life thing. In real life you would such accept in some point that it's zero when it really isn't it's such very "close" to it.It could actually get to zero, eventually there would be less mercury atoms than water molecules, then it's just probability that the atom is contained within the 1000l/hr that is removed.

I can throw one approximation problem if you want to solve it.
