Relation between units of lengths mass and capacity?
There is no relationship between units of mass and either length of capacity. Units of capacity are the cubed units of length.
What is the no of execution units present in Pentium microprocessor?
2 execution units
How much is 29 astronomical units?
29 astronomical units = 4,338,338,250 kilometers.
Why is it necessary to have fractional units?
Not all magnitudes in nature come in integer units.
What is the conversion factor of the metric system?
Depends, what you want to convert to what. To convert between different metric units, powers of 10 are used. For example, a kilometer is 1000 meters. To convert from metric units to imperial units, you have to ask specific questions for specific units, for example, "how to convert inches to meters", or "how to convert pounds to kilograms".Depends, what you want to convert to what.

Do all AC units have freon?
no, water is used in case of chillers...
Why do chillers using CFC-11 and HCFC-123 require purge units?
These refrigerants have higher boiling points than say R12 or R22. Thus when a machine using them operates the low side will run in a vacuum. So any low side leak points will suck in air rather than leak refrigerant out. A purge unit constantly samples the condenser gas and removes the air and water vapor which has been pulled in at these leaking points and periodically releases them to atmosphere while it condenses any refrigerant vapor picked up in the sample mix to a liquid and returns it to the machine.

Does air conditioning units for manufactured homes use water?
Some heat pumps use shallow wells to draw water, transfer heat, and return the water to a second shallow well. All other A/C units using water are called chillers or cooling towers, and even a small unit is larger than a semi truck trailer..
Why did scientist agree to use SI units worldwide Instead of units common at their location?
Scientists must be able to reproduce the results of experiments done by others in order to verify each other's conclusions. Using the same units worldwide removes the potential for error in converting between units or confusion between units which have different values in different places (e.g.: English mile, Irish mile, French mile, etc.).
How do you know whether you have chained fractions correctly when you are changing a measurement to different units?
Select a conversion factor so that canceling removes the undesired unit and leaves the desired unit.

What are the factors affecting the force?
The formula for centrifugal force is mv2/r, all measured in SI units (kilograms, metres per second, metres). Since centripetal force is the opposite, it logically follows that it also depends on these three variables.

How many Grundfos pumps are there?
Grundfos makes and has made millions and millions of pumps. They are the world's largest pump manufacturer, based in Denmark. Annually, the company produces more than 12 million pump units, including circulator pumps, submersible pumps, and centrifugal pumps.
Do heating and cooling chillers use freon?
"Freon" is a trademark name of the the DuPont Corporation for a series of CFC and HFC refrigerants manufactured and marketed by them - thus, it's only actually Freon if it's manufactured by them and marketed by that name. They all use some form of refrigerant, but not all of them use CFC or HFC refrigerants. There are refrigeration units which use straight ammonia, for example.
Are water chillers good for data centers?
There are two possible answers to this question, both pertinent. Water Chillers could refer to a water-based cooling system, where the water interfaces with each piece of server hardware (i.e. "water cooled PCs"). There are also types of A/C units which could be used to cool the entire data center known as water chillers. In terms of A/C units, that would be specific to your data center - this depends on building construction, technology and location. They are typically used where the hot air generated by the A/C units is not favorable and the use of water is more appropriate. An on-site assessment by a qualified HVAC contractor would be your best answer to this - it will depend heavily on your specific situation. In terms of direct water-based cooling systems, there is no absolute answer. I have read about data centers using water-cooled systems, but they are expensive, prone to leakage and likely based on older, less-efficient technologies. Data centers which cool the air around the hardware allow you to use more standardized hardware and eliminate the concerns with coolant leakage and maintenance of that system. In the end, I would suggest that you look at the design with a more traditional approach and consider a water-chilled system only if there are large limitations specific to your needs that a traditional air-cooled data center cannot address.
