Thanks a bunch guys!
That's about what I had come up with, but was having a tough time finding the Cp for my oil... I'll dig some more.
W is the flow rate, in mass or volume flow rate?
Thanks
I have to heat up some oil flowing through a 1" pipe. I need to know the equation (mind is hazy now).
I want to use an electrical resistance heater to heat the fluid. Fluid is oil, about 140W gear oil.
I just want to get into the ballpark to size the heater.
Need to raise the temp from ~0*C to...
Pricej20 did you actually mean direct injection (into the cylinder) or do you just mean port injection?
I've never heard of direct injection propane, hence why i'm asking. Would you "settle" for liquid port injection?
Side question to the other members - can direct diesel injectors be used for...
I'm not familiar with that engine, but i'd bet it's a turbo charged lean burn engine?
It's quite common for the manifolds (and turbo's) to glow red when they are loaded hard.
Landfill gas is a nasty beast, the CO2 levels tend to make it burn a bit hotter as well, if I remember correctly.
I...
I'm trying to make a nifty animate explode / collapse, to show how to build this little gizmo. It seems like no matter how many steps are in the explode, it will only give you 8 seconds, so more steps = much faster movement.
Can I adjust that? ie, 2 seconds per step or something?
Also, is...
oh yes, i'm well aware there are products on shelves to solve this problem, the battery isolator is my option #2... However I wanted to make my own setup (ie a homemade isolater if possible, I just didn't know what the guts are inside..), since I am an ENGINEER!!
hmm, that's kinda the conclusion I came to, if the voltage never drops below say 11V, then I don't really have to worry about drawing huge amps... I guess that's why I never had a fire with my old setup (same thing, but wing-and-a-prayer...)
Yea, I would put a 40A fuse on it for sure, and a...
Exactly, a camper. Yea, I was thinking of mayber running more then one, i'll have to see what kind of drains i'm putting on it.
Your rules here (very helpful, thanks!) is that mainly for lead acid, or do the first 4 go for deep-cycle/gel/spiral grid /Optima...
Yes, I wasn't clear that a head lamp was a head light, or a dome (above your head) light... Anyway, i'll pick some and test, since I could fit 4 (or 10) small courtesy lights in easier then 4 head lights.
Functionally dead at 12V? huh, learn something new every day, I thought it'd still be ok...
I was thinking the "to be charged" battery would be a marine deep cycle, or an Optima or the like. And would most likely drop it's voltage, but not sure how low, time will tell.
I won't need the bulbs for lighting purposes most likely, it probably won't be visible, but I may use tiny lights...
Wow. Thanks Gunnar (and others)!
Lightbulbs eh? just simple 12V bulbs? wired in parallel to each other, series inbetween the batteries?, like 4 or so say?
I'm guessing the lights will see the voltage difference, say 12V max, and will light up, (and create resistance to make the light?), and...
I have a 12V dc battery, which will be fully charged (and will be charged via an alternator), and a 12V dc battery which will be at any level of charge, and when the switch is thrown, they will be connected in parallel, so the fully charged one will charge the discharged one. They will be...
