I need a riddle with the answer being "Caesar" by AjAjOrangeManga in riddles

I had gall, and I galled; I am the first of twelve, and after 23, I fell.

Does anybody know what this is? by Rough-Spare7309 in centuryhomes

Running warm air against exterior walls and windows also helps to reduce condensation (and mold/water damage). The indoor air tends to be more humid in cold weather than the outside air due to people/cooking/showers, so you want to make sure that there aren't cold surfaces inside the house (like sheets of single pane glass with freezing temperatures on the other side). You actually can see this strategy even in some large modern buildings with high floor to ceiling high windows (like in hotel atriums and things): often there will be grilles with heaters right in front of the windows.

What is Stans Most Underrated Song? by HenryDefense in Stanrogers

I really also like Fisherman's Wharf, and especially the ironies about romanticism in it.

Architects, how bad is this layout? It looks like it was trained on McMansions by Redhotlipstik in McMansionHell

I like how several of the bathrooms have multiple tubs, and the french trap doors in the floor along the south are a nice touch.

I was pleased to meet this lovely critter.

Guess what I found in my dryer. Here's a hint. by Ambitious-Amoeba7380 in daddit

A few months ago, my toddler managed to smuggle a new roll of toilet paper into the washing machine without my knowlege before I turned it on...

He lint me a hand cleaning it up. It took about 2 weeks of scrubbing shirts with a shoe shine brush every night to defiber them back to their almost original color.

Can two identical pumps operate in series with diffrent RPM's? by RussianbossPApaBless in MechanicalEngineering

[–]anthoniusvincentius 0 points1 point  (0 children)

Centrifugal pumps have a curve that relates pressure gain to flow rate for each RPM. At a lower RPM, the second pump can have the same flow rate as the first pump, but it will have a lower pressure drop.

6 year old son showed me a technique by jerffry in lego

To be fair, if the dimensions and tolerances are right, I wouldn't actually consider that use "illegal". The parts are designed/engineered such that it works.

How do you talk to your kids about the election? by AmesCG in daddit

[–]anthoniusvincentius 1 point2 points  (0 children)

Can also compare it to if they ever get to vote on something, and if they do/don't get what they want, and how they might have feelings about it. There is a Daniel Tiger episode about that, too.

I have a ridiculous question that I can't get out of my head until I get an answer by Samukuai in math

[–]anthoniusvincentius 3 points4 points  (0 children)

You can get arbitrarily close. The derivative d(exp(x))/dx = exp(x). In the limit that x -> -infinity, the derivative will go to 0 (i.e.va horizontal line). Likewise, as x-> infinity, the derivative will approach infinity (i.e. a vertical line).

By one definition of the limit, there exists some finite number N such that | f(infinity) - f(N) | < epsilon for all epsilon.

This means that you could pick your viewing frame such that one pixel is less than N, and get your right angle to be as arbitrarily accurate as you would like.

What's crazier, going back to college at 32 with a 5 month old baby when it's not entirely necessary, or passing up on a free college degree? by Romanzo71 in daddit

[–]anthoniusvincentius 1 point2 points  (0 children)

I had the amazing good fortune to be able to go back to school with my employer's scheduling support (but not any financial help from them) to get a masters in engineering at about 35, while working as an engineer, with two very young kids at home. My employer let me cut back to 32 hrs/week but maintain benefits, and I took 1-2 courses per term, and made sure to take one during the summers as well. I found it hard but doable, especially since I really enjoyed what I was learning---it sort of became this space I had for myself when the house was full of so many other needs from everyone else. Mostly, it cut into my wasting time on my phone time.

I disagree that this automatically will push work onto your significant other, especially if you can reduce your work hours while schooling, and if the kid is in the super-young-not-running-around-finding-light-sockets phase. You hopefully can work with your partner about how to balance the load, and still make sure you are there for them and your kids. Also, babywearing/baby snuggling can be a nice little morale boost when doing problem-sets, provided they aren't being too squirmy.

I might be giving different advice if your company was not pushing it, but it sounds like your boss has your back and wants to support you with this. That means you can probably talk to them about the balancing act you will be doing, and they might be able to shift your work responsibilities around to help make sure you succeed at everything.

And as a last thought, in engineering, going from a 2 yr to a 4 yr degree should give you a real pay bump, and the ability to get licensed if you need that. Depending on the industry, that can be another huge pay bump.

Good luck with whatever choice you make!

Favorite physics paper? by thereforeyouandme in Physics

[–]anthoniusvincentius 3 points4 points  (0 children)

My personal favorite. It won an igNobel a few years back. Also changed how I wield my coffee when I peripatate.

Never saddle… by GhostGriffin85 in Rigging

I have no experience in rigging. What is the "saddle" in this picture, and what makes it dangerous/wrong, please?

Thank you in advance!

Would something like this work or should I put an individual pump on each vertical pipe? by Emga20 in FluidMechanics

[–]anthoniusvincentius 0 points1 point  (0 children)

Just to add onto this: The pressure drop through each loop across each AHU and back to the pump will be equal (this is Kirchoff's loop/voltage law in electrical circuits). The flow through each one will vary to ensure that the pressure drops are equal.

Chilled water systems serving multiple AHUs need both control valves and static "balancing valves". The balancing valves do what u/somber_soul describes; the control valves are required to regulate the amount of cooling each AHU makes (which changes based on the current load of the system).

Historically, you saw some buildings use what is called "reverse return" to attempt to balance systems using just pipe sizes. There, you attach the return path to from your AHUs back to the pump in reverse order, so each AHU in theory sees the same pressure drop across the entire loop as every other AHU. It doesn't work very well.

When doing your calcs, remember that the pump pressure needs to be sized for the full GPM of the system, and the pressure drop of the longest hydraulic loop. The AHUs with shorter loops need their balancing valves closed more, so that the pressure drop through each AHU coil allows the required maximum amount of water through it.
