What should you do if the low pressure line is insulated and sweating outside the insulation above a suspended ceiling and dripping on the ceiling causing mildew?

What is your question here? If you want to keep the insulation from sweating get thicker insulation. You probably have 3/8 thick insulation; increase to 1/2 or 5/8. It is possible that your suction line is freezing up and when it thaws it soaks the insulation causing it to drip. If you can't prevent the leak, use a vinyl ceiling tile, like Ceilume, in that area. It won't absorb moisture and is easily cleaned.

Wires are insulated to prevent electrical shock. Think of electricity in terms of water. Say you hook up a garden hose and turn the handle on the valve. If you instantaneously freeze that picture for a second, there will be high pressure at the beginning of the hose where the water is and no pressure at the end of the hose where the water would come out. Voltage is very similar to that in regards of voltage being a potential difference in electrical pressure. The insulation on the wire, similar to a garden hose with water, ensures that the electricity follows the intended path. Added: No wires are insulated to keep you and your home safe and to keep them from grounding out on anything metal and causing fires.

Acoustic insulation of airborne sound, also known as soundproofing are any means of reducing the pressure of sound from the sound source.

In general, volts affects the spacing of conductors and the level of insulation they receive. The higher the voltage, the greater the electrical 'pressure', requiring conductors to be more separated and/or insulated to prevent shorting and arcing. You should always use wires and connectors rated for your voltage or greater.

Airplanes are NOT "suspended in mid air" - they move through the air and are supported by 'lift' derived from the differential air pressure above and below their wings.

Yes, water can be boiled inside a closed insulated vessel by decreasing the pressure on the surface of the water.

if it's dripping water constantly even when cold most likely your pressure reducing valve on the in coming water is letting in more water than it should causing the pressure to rise, if it just happens when the boiler is calling for heat it's probably your expansion tank, it could be water lodged and needs to be drained and re pressurized or replaced. make sure the pressurizer relief valve is not dripping before your boiler reaches 30 psi, that's what they are usually set for on house boilers, if it is dripping before reaching 30psi it's a faulty pressure relief valve that needs to be replaced

What size tap, how much pressure, how big a drip? No way to answer without enough information.

no. Compressed nitrogen need not be insulated. Liquid nitrogen is always insulated. Typically compressed nitrogen is stored at high pressure(over 1000 psi) and liquid nitrogen is kept at less than 100 psi.

If the water is dripping, I would replace it just to be safe. It doesn't cost much money.

soft layers of insulation, neoprene rubber, and Kevlar, which both hold pressure and protect the astronaut.

The height over sea level and the weather conditions cause variations in air pressure. Increased air temperature will reduce pressure. Suspended water molecules in the air will increase it. It's not the wind!

Atmospheric pressure changes with the weather. Cold air is heavier than warm air. Suspended particles or moisture will also increase pressure. http://en.wikipedia.org/wiki/Barometer

to check the leak in th transformerAnswerThe term, 'pressure test', has nothing to do with 'pressure'. It is a test in which the integrity of the insulation of an electrical component is tested by applying an over-voltage across it for a specified length of time. Pressure tests are conducted prior to commissioning high-voltage equipment.The applied voltage is a DC voltage, and its magnitude, and the duration of the test, depends upon the voltage rating of the component being tested. It is often necessary to perform more than one test, depending on the configuration of the component being tested -e.g. line-to-line, line-to-earth, etc. The test is not intended to break down healthy insulation.In the case of a transformer, a pressure test is conducted to ensure the integrity of the inter-winding insulation, and between the windings and earth. Transformer oil is also subject to independent pressure testing, but this is normally conducted in a workshop or laboratory,

Air pushes in all directions at the same time. That why when you blow soap bubbles they are perfect spheres when they a still suspended in the air.

I get that all the time, also it usually means the membranes in my nose are bloody, not dripping blood but very thin, my left eye is the only one that waters

You heat the water in the boiler chamber to produce the steam. The steam under pressure rotates the blades of turbine. You have a shaft attached to the turbine. You have the coils of insulated wires wound around the shaft. This shaft rotates between the powerful magnets to give you electrical energy, through the insulated wire.

Commonly liquid nitrogen is stored below 100 psi. It can be stored at 0 psi. All liquid nitrogen tanks are insulated to stop heat from boiling off the liquid.

found out it was the oil pressure switch dripping down on to exhaust pipe collecting on heat shield, thanx anyway

Rigid container implies the volume stays constant. The pressure will increase, and if the container is well insulated, the temperature may also increase.

I have an '04 and my lights are different than yours. However, the wavy lines probably indicate level, so you probably have a low oil indicator demanding that you add a quart. My Montana has two oil warnings: a dripping oil can says low oil pressure. A dripping oil can with a wrench below it means I should completely change the oil.
