Everyone likes different things, and that’s okay.
The important thing is to recognise that some people will find things interesting, which you have no interest in whatsoever, and vice versa. This is important, and probably very advantageous from an evolutionary point of view. No-one can be an expert at everything, so it helps if we specialise, and if we all liked the same things, no-one would do the other stuff.
All of the foregoing is so that when I say that on my recent holiday I did some recreational maths, you won’t give me a hard time about it. The maths I did is here: Time required to drain a tank
While there are plenty of references for the simplest form of this calculation, what you get here is:
- A complete derivation
- Inclusion of friction losses through fittings and valves
- Consideration of non-atmospheric (pressurised) tanks
- Not having to wade through forum posts of vague queries, unhelpful half-answers, and opinions from people who don’t really understand physics (and probably shouldn’t be on that sort of forum to begin with).
I’ve also updated my menu bar at the top of the page, to try to make some of my questionable content easier to access.
Hopefully soon I’ll make time to do a few more posts, but since that involves actually finishing some of my projects so that I have something to blog about, it might be a couple of weeks before I have anything really interesting to say.
