this is quite late but as an electricians apprentice i have seen this done, maybe not a smoke detector into a camera, but you can run wires like you are explaining simply by lets use your detector as an example IF it is wired through the house hiddenly then you can cut one of the wires, and connect three wires of slightly smaller gauge to it and pull it through (if there is no abursed 90s or multiples of them which would break code) and pulling the other end to or connect a fish tape to said wire and pull it through.... small, short runs can be done this ways so your example is not far fetched...

@ShaggyRogers1 9 ай бұрын

Running new wires in a house without touching attic or crawlspace isn't that difficult. It's entirely about placement of the new box compared to existing setup. If you have an outlet or switch on the same wall, you can just piggyback off the existing circuit. Running the wire itself is just a matter of cutting out the space for the new box and using a flex rod shoved up/down the wall. Anyone with experience working the electrician trade would easily be able to setup some cameras, and the "remote to your phone" is the most common setup to install these days.

A kinked hose at 1500 psi wouldn't be too fun to witness. Also, water jets often use 10k+ psi with garnet chunks mixed in, and those can take hours to cut through some stones depending on dimensions. With only 1500 psi, a fire hose nozzle, and sand at best, he would be lucky to cut through that in days. Not to mention good luck holding that hose with 1500 psi at that volume coming out. Hell, a decently powerful pressure washer is around 3000 psi at like 2-3 gallons per minute and those things can be difficult to handle. At 1500psi even 2-3 gallons per second from that fire hose would be impossible to hold on to (hydrants can range from like 400-2500 gallons per minute, or around 6-41 gallons per second)

If I remember right the idea was to use very high pressure and low volume to create large amounts of steam to put the fire out. I could be wrong. By the point I was a fire fighter all we used it for was a wild land fire. If memory serves it was like 750-850 psi and it was a hard rubber house with something similar to a pressure washer wand.

i remember from my time in fire and rescue we had a few different nozzles for different things. yea sure normal sprayer was standard but we had one that looked like a fork that could be secured to a wall, the pressure is then upped to begin cutting through wood, stone and metal til it makes a tiny hole in the other side of the wall. the way it cuts through the wall is very fun because if it manages to not hit a radiator or a pipe it will sudden fill the room with a high pressure mist of water to suddenly bring temperatures down. from what i knew we didnt have any that turned the hose into a straight up water cutter thats what we have the other cutters for.

@AustinWesson Жыл бұрын

Working with fuel trucks, we pump at a maximum flow rate of 600 gal/m through a 2 1/2" hose not allowing it to exceed 55psi against the nozzle or 140 psi from the pump to ensure no damage to the equipment. 600gpm can usually be obtained (best case scenario) at about 120psi from the pump, 10 gallons a second. 1500 psi would be something like 7500 gallons a minute, or 125 gallons a second, assuming the hose is the same, but that nozzle looks conical so it would increase pressure out, reducing the necessary flow rate for 1500 psi. Still insane numbers.

@Sara-L Жыл бұрын

...No. 60-80PSI at the hydrant means 60-80psi at the nozzle. There's a reason you need a gas guzzling pump to "charge" water to certain pressures. Pushing water through a narrower hole is the same as slowly shutting a valve on a faucet. It slows down and backs up the flow.

@@Alucard-gt1zf There are two restrictions to the volume per second expelled by a firehose: 1. The speed of the water 2. The size of the nozzle Increasing the PSI pushes the water faster so increases 1 while 2 is constant since the nozzle doesn't change size, therefore you know you push a higher volume per second and will get pushed more. An average firehose at 1500 PSI will launch you in the sky, it's enough to lift a small car.
