What typically happens when you drop a hair dryer in a bathtub?Say it's leaking water . What would/could happen?

Nothing unless you plugged it in first.What typically happens when you drop a hair dryer in a bathtub?
And that's really the point; don't plug in stuff that isn't designed for wet use.
Yeah what happens when you do that?What typically happens when you drop a hair dryer in a bathtub?
Sorry I`m new here ! But would you buy an aircooled car if you can get a watercooled ?Air cooling is just as effective as water cooling, each just have their strengths and weaknesses.
The whole water and electronics thing always makes me laugh though. Computers have been water cooled for decades...
Youre light should never be powered any time you are working on it... It really is that simple. Anyone who does that deserves the darwin award. (knocks on wood). lol
There's a thread link in my signature line. The modern water cooled COB LED era starts on page 129. I'd like to hear your thoughts.Wow great idea water cooling the array, I like it. I know a little about moving heat energy using water and I can attest that you can move a TON of heat with water using very little effort and almost no noise if you set it up correctly. The electricity/water concerns are easily managed with good light design and ground fault circuit interrupters @fearnoevil if you have any data from the smaller tube please post it. Also, do you know flow rates and fluid temperature changes across the bar? These would be great data to have.
My state just became legal and I'd like to set up a modest grow room. I have a 20 year old mh/hps but it would be way too hot for the small space I'd like to set up. Been researching LEDS and think diy cob build is the way to go, but still concerned about the heat. Was originally thinking passive heat sinks but the water cooled option is so intriguing. Even if you are running relatively warm water i would guess the ability to conduct heat away from the cob is still quite high. Does anyone have any data from running relatively warm water (say 60C/140F) under the cobs? At those temps it is easy to dissipate the heat outside the grow space.
Is that possible? You have to have an air leak somewhere? Did you to a pressure test before filling with liquid?Been running my water cooled setup for 6 weeks now.
Need to figure out a way to stop the coolant loss. Dehumidifier manages to draw out the coolant even tho the res is air tight.
I guess I could keep topping it up tho since 6 weeks for 220ml loss isnt too bad.
Its all simply a function of how fast you can remove heat from the system vs how fast your light and pump are adding heat. The temperature then of the system will be more dependent upon ambient temperatures if you are using a radiator, as it will reach an equilibrium at (x) degrees above ambient temp. As long as your pumps can handle the heat, there is nothing wrong with running hotter water through your system.Was originally thinking passive heat sinks but the water cooled option is so intriguing.

Homeboy lost a whole cup, I think he'll live lolIs that possible? You have to have an air leak somewhere? Did you to a pressure test before filling with liquid?
Agree, small amount, completely manageble. Its just from my experience, or lackthereof?, in hvac. I dont fix the crap, Im the guy that sells the crap, then gets yelled at by the customer when it breaks. But I usually hear or can find out what the solution was if I want. I've just never seen an instance where a liquid in a sealed system or refrigerant within a system go missing without a leak existing somewhere . Its the investigator in me, now I'm curious and have to know. I'll ask my service guys tomorrow whats possibleHomeboy lost a whole cup, I think he'll live lol
I lose a little on a regular basis. It's not an emergency unless there's enough loss to affect performance.Agree, small amount, completely manageble.

Theres a million ways to skin that proverbial cat. Why dont you share more info on what you want to achieve.So hydronic uses a sealed system under pressure, are you guys doing that? I hear the word "reservoir " and sound like an open system subject to evaporation? I ask because I am thinking of going water cooled in my new place and I have been studying up water cooled hydronic systems to figure out all the pieces I need to put together.
It would be really nice if one you guys uploaded a diagram of your system to see how it's all plumbed together.
