  • I have to admit that even this Old Texas sauce wasn’t quite as good as I had hoped.

    Sometimes the local butcher has beef stock for sale which is liquid gold. Then I just take the pan which I used to sear the steak with, add some of the steak trimmings, shallots, rosemary and sage, give that a good roast, then I deglaze the pan with beef stock and red wine.

    I let that reduce for as long as the steak needs to get to ~50°C in the oven. Filter it, add some corn starch water and butter, hey presto, great steak sauce. When the sauce is done, the steak is usually at 55°C and done as well.

    Sadly, the butcher didn’t have any beef stock this time.

    Let’s do it:

    The phenomenon that causes divers to be trapped is called differential pressure, or Delta P. It requires surprisingly little Delta P to trap divers in such a way that they can’t free themselves.

    The formula is simple: F=Δp⋅A

    Δp = Differential pressure, A = the area the differential pressure acts on, in our case the cross sectional area of the pipe.

    Example:

    30 cm pipe => A = π⋅(0,15)² m²

    Delta P only (!!!) 0.1 bar (= 10 kPa).

    F = 10,000 Pa ⋅ 0.07 m² ≈ 700 N. This equals roughly 71 kg of weight.

    Now, let’s try this with the numbers above. Unfortunately, we don’t know the diameter of the pipe so let’s again assume 30 cm:

    Δp = 21.375 - 14.7 psi = 6.675 psi ≈ 0.46 bar = 46 kPA

    F = 46,000 Pa ⋅ 0.07 m² ≈ 3250 N.

    => You would be sucked to this pipe opening with a force of roughly 330 kg. In other words, you’re fucked.

    For fun, let’s assume a 50 cm diameter pipe:

    F = 46,000 Pa ⋅ 0.196 m² ≈ 9020 N.

    This equals roughly 920 kg of weight.

    => There is absolutely no escape here and I think it’s safe to assume the diver would be sucked through that pipe.

    And finally, to answer your question (I’ll skip the math here), a 10 cm diameter pipe with the same Delta P would mean 37 kg of weight. I think it would be possible to escape in this scenario, but it’ll not be effortless.



  • the abrupt “time to leave” even if you’re not done

    Seems like you went to the more touristy places. Or Munich. Or a touristy place in Munich. They tend to be a little brusque and unfriendly there… It really pays off to look for places on Maps which are highly rated and a little off the beaten path. Some real gems there. I could name a few restaurants in Berlin which serve awesome German (!= Bavarian!) food that isn’t repetitive.
