    Fluid dynamics in rotating rigid container

    Pascal's law seems contradictory to what I would expect. If the pressure in a hydraulic system is equal everywhere, but you have a fluid, completely filling a rotating cylinder, wouldn't the force on the walls be greater than the fluid pressure in the middle due to the centripital forces...

    confused with what's going on, ground/neutral issues, tripping GFCI etc.

    I'm not an electrical engineer but I thought I'd get better responses here than if I posted in the hobby section. I'm having a strange issue and I'm a little tired to get my head weapped around it for the night so I figured I'd ask before I jump on it tomorrow. My shed has a sub panel...

    Python is (in some ways) a total mess! How should I plan to go from here?

    so I'm learning python and enjoying it for the most part. But holy cow! If you want to use python 3.8 this other thing you installed 6 months ago is not compatible yet. If you want to use this module, which hid dependent somehow on this other module, well, both modules have to match, and be...

    Ductless mini split systems that can interface with a control network

    Debating control options, controling zones independently vs. one thermostat. I know mitsubishi (If I remember correctly) allows an interface that can control multiple mini splits. They currently have some more consumer friendly program that allows customers to use their smart phone and do...

    residential unit, modification, fighting mold, mildew, unit improvements, etc.

    At my moms place, the unit was recently serviced and we were told, and shown it had mold inside. Not sure if it was mold or mildew. It was cleaned from the unit and shortly after the whole house started to smell of mold and mildew. Hard to say if it's mold or mildew since there's so many...

    removing bearings from aluminum case

    ok I've tried several methods without the best tools and it seems the tools will be required. My experience has led to the development of several questions I'd like to discuss. I tried hearing the case in an oven to 265 degrees with a papertowel filled with water inside the bearing to keep...

    Game plan to start my own little business out of college

    Tell me about some small engineering jobs you can do and average pay I'm considering opening up my own practice when I graduate. I'm not chasing the money, I want the satisfaction of doing things my own way, for the better. (More on that after my questions though) I've looked up all the...

    Applying Crank Case Vacuum in single cylinder engines

    Hey guys, so I've considered that V8s and even inline 4's get great benefits from vacuum pumps on their engines. I would like to apply this to a single cylinder, here's some things I'm considering: [ol 1] The engine may provide an adequate vacuum pump for half of the crank case revolution...

    Exhaust drone causes, and reduction techniques

    Hey guys & gals of the ENG-TIPS forums! I've been working trying my hand at finding good exhaust drone cancelation solutions, because I'm trying to further my understanding of sound waves and automotive engineering. I work in R&D, and I took a project on for someone who bought an aftermarket...
