Is 'water Tank with Inlet & Outlet Valves Closed' a Open System, Close System Or Isolated System? Th

Based on your definitions and assuming the tank is closed on the top then the system would be a "closed" system. For it to be an isolated system it would also have to exist in a perfect vacuum with the boundary of the vacuum at the same temperature as the tank. That way there could be no energy transfer by radiation, conduction or convection. As to why this matters I can only guess the question is designed to determine if you understand this aspect of thermodynamics.

1. Hot Water Heater leaks through drainage spigot after flushing

Those plastic shut off valves on water heater tanks are obviously very cheap and probably low quality as well. There are likely two main reasons that the valve leaks (maybe three). Mitigation information:

2. what are the measurements (inches/centimeters) of a trumpet bell and valves?

Which trumpet? The reason I ask is because different manufacturers use different dimensions and there is even variations between a manufacturer's models

3. Hot water is not hot enough after the water main was replaced. Why?

You call the same plumber and tell him that supposed to be so is not good enough. He needs to be sure it IS so. Whenever you mess with the plumbing it knocks loose all kinds of stuff that was in the pipes and is now somewhere else. the crap can be building up and clogging your faucet filters, valves, and shower head. He should have flushed the lines at yours or anybody elses places after chnaging out the pipe(s). What about your bath tub? does it have better water flow and stya hot longer?

4. How Can My Valves Operate So Productively Regardless Of A Very High RPM? Pic?

The design has alot of do with it. People dont understand that in alot of thing that you buy, the good ones will usually be more expensive. Not because of the name on it, but because quality control and research/design that keeps up on improvements. The hardest thing is adusting the valves on an RX7 rotary engine.

5. where are the check valves for the air suspension on a 2000 crown vic?

If it's factory air ride they have their own built in air compressor. That's how the suspension can compensate for increased loads, the compressor builds up the air pressure, so no need to add it if you could. If it's down on all four wheels, first check the trunk, they have a switch in there that turns off the air suspension. Not sure on yours, but the earlier Lincolns and Mercs you had to turn off the air suspension before raising the vehicle on a lift. If you did not the bags would extend and pop and you had an instant low rider. Hopefully for you someone just bumped the switch with a bag of groceries and flipped it off. Normally if there is a fault in the air ride it will set off a lamp on the dash. So it seems like that may be your problem. If it's not, check for a blown fuse, but that should set a level ride light on the dash. If it's none of those, plan on a not pretty bill to fix it.

6. On an old New York apartment radiator, with two valves, what do I do to only have a little heat?

steam comes in through larger pipe at bottom of radiator."leave this valve opened all the way,closing even alittle will cool down steam and turn into water. use only top valve regulatortotadjust temp. the banging you hear is the hot steam hitting the colder water left in radiator,that's why you leave bottom valve opened always,stay warm

7. What are water line measurements?

Water line measurements can be applied to construction projects involving water main installation. Linear feet of pipe, number and size of shut off valves, pressure reducing valves and fire hydrant valves are all things that need to be measured and accounted for. Granular backfill is usually applied to half way up the pipe and plastic wrapped pipe is common in acidic soil conditions. The bury depth will determine the amount of compacted fill required and to finish the job the trench needs to be seeded and/or sodded.What are water line measurements?

Would Doing a Pressure Check Expose a Leak on an I30 Infiniti
IT would, there are several pressure tests:. .1. Compression test of cylinders to check rings and valves seats. .2. Cylinder leakage or leakdown test to check rings and valves. It is more accurate than above.. .3. Cooling system pressure test to check all aspects of cooling system.no cap seems to fit my galvinized supply hot and cold water valves for the shower?Borrow a digital caliper or a tape measure and measure the OD (outter dimension) of the pipe to cap to get the ID (inner dimension) of the cap needed. Then do what old contracter saif with the teflon tape on the pipe. Also if your handy you can die the threads into a blank cap, that means put threads into a blank cap with a die tool if no size is availible at the store and retap the threads on pipe to even themn out.what are some cars that are fast when all stock?i have a ford sho its a taurus with a bad *** 224 hp motor in it mines a 92 i would say get a 92-95 they were the best if you get the 96-99 and the cams r not welded they will bend valves and 89-91 jsut were more box likehow do you use a PEN TIRE GAUGE?they are for car type [schrader] valves some bikes have another type, presta a pen gauge would let all the air out of one of those for sure wleCan i install HKS SSQV on my Nismo 370z ?That sound is left over boost being blown out the Blow Off Valves.

Good LuckHow to replace a Hot Water Boiler Relief Valve?I assume you are referring the pressure relief valve on the boiler water vessel, and not the oil line relief valve on the burner. The pressure relief valve is a very important safety device that needs to be properly sized and fitted to boilers and pressure vestals. It is sized and built to relieve as much as, or a percentage more than the BTU output of heat which it's burner can produce. It's inlet size and outlet sizes must never be compromised. It should match what was original on the Mfg.'s specifications on the name Tag of the boiler. (DO NOT TAKE FOR GRANTED THAT THE PRESENT RELIEF IS THE ORIGINAL.) Read the info on the valve tag and compare with the input and output rating on the boiler burner ratings unless your the original owner and know its correct. Because of safety reasons I would recommend.that you allow a professional HV-AC Boiler Technician to change out the relief. He would turn the boiler off, secure the water side and burner side and valves to Isolate your boiler (so as to not drain your system) take the pressure off, drain just a bit and remove the relief ,with the proper wrench. ********Safety note: Most Reliefs are built of soft metal (Brass) or Bronze when fitted out or into the pipe fittings it is very important to use the proper wrench and not place the wrench on the body or any other place on the valve but the proper shoulder made for the proper wrench. When the new valve is installed the the boiler needs to be placed back in original settings of valves and switches. Fill water back on, Vent air from system, fired and tested for leaks. The above safety notes are just a few reasons to have a Licensed experienced boiler man do the job Please be careful, Blessings RangefinderIntake and exhaust valves? How do they know when to go off? What controls them? How do they work?They are controlled by the camshaft. When the cam opens the valve up, the spring on the rocker arm pushes the valve back shut. I found a video for you that shows what I am talking about much betterHow would you stop someone from trying to blow up a bunch of propane tanks, M80s, and alarm clocks in a car?Most people do not have a bunch of propane tanks and M80s around their home. And even if they did, they would have to know how to rig a bomb from it. Today's propane tanks have safety and check valves on them. Like this idiot in New York, he used the wrong type of fertilizer so it did not have a chance to blow up. Even with Timothy McVey, the police were just a few steps behind him and if he had waited 2 days longer, he would have been caught before the blast. And even with his bomb, it was just plain luck (for lack of a better description) and poor building engineering design that caused that amount of damage. His home made explosive was 3 rate at best. Send me a mail message and I will explain how the bad engineering design of that building played into the destruction. JD
