Why shouldn't you have any air bubbles in a pipet?

If there are bubbles of air then you will have less liquid than you are intending to have. Assuming you are calculating density via measurementof mass then the mass you get will be less than it should be for that volume of that liquid. As a result the calculated density will work out lower than it should do.

isn't liquid suppose to get in the thing?\n\nit sounds like an air dry outside will help if anything will

The bubbles are steam, or water vapor.  They are NOT from hydrogen and oxygen.

Sounds clean.... bubbles included?

Square pipe.. Why do you ask?

Air bubbles float up in water due to buoyancy because they displace the weight of water equal to their volume.  Water pressure is greated at greater depths therefore there is slightly more hydraulic pressure upwards on the bottom of the bubble than downwards on the top and the bubble is pushed upwards.  As the air bubble rises the pressure is reduced allowing the bubble to grow and it increases in volume and buoyancy as it travels to the surface.  This effect can also release and grow excess nitrogen in the blood of a diver causing growing nitrogen bubbles that cause great pain or even death and is called the bends (occurring especially in large joints that bend).\n\nOf course, soap bubbles float up in air due to air currents.  In a still room they float down to the floor and pop!

hydrogen sulfide, carbon monoxide, and carbon dioxide.  Plus, you have to be concerned that there might be no oxygen in the air.\n\nEntering a sewer should be left for people trained in doing "confined space" entries.

Shouldn't be!\nIf you are experiencing an odd smell I suggest you check the flue (see Link 2.).\nIf you are worried about fumes in the room then there is probably something wrong with the flue and the correct air-flow is not occuring.

crack pipes with water?

Ionization occurs when air is exposed to high VOLTAGE, not high current. If you're going for cheap and easy, just put an ionizing air cleaner next to your aquarium's air pump.

Not the surface area of the water in the bowl, the vacuum in the bottle, or partial vacuum and the height of water in the bowl. The bottle will let air from the bowl in as soon as the water in the bowl drops...see the bubbles?

ESD (Electric-Static Discharge) Workboots, explosion proof switch and power boxes with a positive pressure airflow to keep dust from entering. Absolutly no open contacts where a spark may occur should be out in the open.  make sure all pipes carring the powder are grounded so they will not build up a charge; better yet, ground anything metal to keep from building a charge.

The bubbles are not "air" as most of the other answers claim; they are gaseous water, otherwise known as steam.  reverie's assertion about water pressure is also incorrect.  In a pot, the bubbles primarily form at the bottom of the pan because that's the hottest part of the pan and water.  The water there gets above the boiling point (212 F) and changes to steam.  At first, surface tension keeps the bubble stuck to the pan. But when enough steam is generated to make the bubble large enough, the bouancy of the bubble forces it to rise to the surface.

What do you mean by the outlet temperature not being uniform. Do you mean not the same over time? Or are there multiple outlets and the temperature from each outlet is not the same?\n\nIf the inlet and outlet channels or headers are not designed carefully to allow for good fluid dynamics then there can certainly be portions of the exchanger that is not getting the same flow as other portions.\n\nWithout more information, I can not see how an energy balance will help solve the problem.

OK if you mean water only I assume that you require to dry out compressed air lines.  This is done by passing the air through an air drier as the air is cooled the water is separated and discharged to atmosphere or drain.  This is one method I am not sure about others.

your question does not make sense. I think you have a program running, or your CPU is getting hot. If it's too hot, that's why the fans are running, and you may have a lot of applications running, or you may have dust. DO NOT USE A LEAFBLOWER!!! \n\nIt can bend all the transistors and electronic to bend. Use a C02 can that compresses the air, it's much more gentler.

`im forever blowing bubbles..?`??
