Re: Heating up the car with snow

Effectively, no... There should be no difference. When your engine is cold, the thermostat that regulates the flow of coolant from the engine to the radiator is very nearly closed. To begin getting heat to your defroster, the heat generated in the cylinders needs to conduct through the block and hea...

Re: Thinking about engineering major, Any advice?

I signed up for mechanical engineering before I even looked up what it was. It just sounded like what I wanted to do. I never had good math grades in high school, but I am very hands on. I decided to push through, and I ended up with straight Ds in Calculus 1,3, and 4. I got an A in #2 because I dro...

Re: "Wire" Gun Plausibility

Well, how big are we talking here? If you've ever seen a machine that makes nails, you'll know they make nails in a hurry. Fast enough, perhaps, to feed a rail gun with a rate of fire similar to that of a stationary machine gun? When you say "Wire" what size are you talking about? the size...

Re: FIRST polar vortex? Oo

I honestly didn't know "Polar Vortex" was a legitimate thing. I thought it was just some made up term they threw on some cold weather to bump up ratings. I still think it's silly they're naming winter storms now. Guess they haven't gotten over the lack of hurricanes in 2013...

Re: Do I need new computer hardware?

A number of years ago, I was setting up a computer lab at school with Windows 7. We did it the semi-hard (normal setup of one followed by physically pulling HDs and cloning them) way because we're MEs and we don't know any better. Everything was fine, but at one point in the setup, we came across th...

Re: Early Human Diet

I always liked this idea that when we were able to secure more reliable sources of food, our ability to run long distances became less important. Then, when food became a little more scarce, we said to hell with running, let's make this hoofed beast carry our now out of shape butts.. Later we decide...

Re: Molten Metal Bubble Blowing Contest, In Space!

Cool, so I'm actually an engineer, and I work in a foundry. I work with molten metal pretty much on a daily basis. I deal primarily with bronze, but that's not too far from steel from a casting point of view. Really I don't think lasers would be the way to go. You can't just take raw ore and turn it...

Re: Worst thing you've seen in a lab

It does creep me out a bit when I walk by those giant canister of various gasses in hallways at MIT, and sometimes they are just sitting there, hooked up to nothing, hissing, with no one in sight. The big shiny ones with lots of valves and fittings at the top are usually self refrigerating tanks (I...

Re: Physics/engineering help - heating

Seems to be some pretty complicated solutions to what I would feel is a pretty simple issue. I say that because It is indeed a question of heat transfer as opposed to heat capacity. I see two easy ways to handle this problem realistically. My solution requires some twerking around, but can be done w...

Well, this one was an ME lab. We were running an experiment through our weir tank. Flow through an open channel if I recall...

This is a bit of an OT aside, but I'd be willing to bet that we can already do this. Flavour chemists are wizards about this sort of thing.

Re: Sizing solar power needs for a DC fountain pump motor?

I'm not too big into solar panel capacities, but what I do know is that you should consider that your panel needs to collect at least enough energy during the day to run all night too. Also, a cloudy day will result in less power to charge. Finally, a deep cycle battery is more tolerant to deep disc...

Re: Electrical induction in water

It's just odd, as far as I can tell, the cathode and anode on my laser tube are completely separated from the coolant cavity by a layer of glass.
