Why is reactor coolant water kept contained in the primary loop instead of allowing it to mix with the feed water and leave through the cooling tower?

Reactor cooling water is potentially contaminated with radioactive elements and you don't want those to be released into the environment, so it is kept in the primary loop.

How does gas affected when air is heated?
If the question is "How IS gas affected when it is heated":When gas is heated, it's volume increases (it expands).If the gas is contained within a chamber, the pressure will increase instead.
Melting of butter can be change reversed back?
Yes, it can be brought back to solid by cooling. Because butter has only changed its state, which is a type of physical change. But some substances solids change their chemical composition instead of changing to liquid form, like Sugar. Sugar on heating turns red then black. Sugar cannot be brought back to its white solid form by cooling.
What property of copper makes it suitable for a saucpan base?
Copper is a suitable saucepan base because it is very thermally conductive, thus allowing efficient heat transfer between the pan and the burner. It is also resistant to oxidation, so that it maintains its conductivity instead of converting to less conductive salts.
What are the advantages and disadvantages of LNG dual mixed refrigerant liquefaction technology as compared to LNG propane pre-cooled MCR liquefaction technology?
Operation in arctic climates poses additional challenges. The main challenges from a process design standpoint are, of course, the low ambient temperatures and the wide range of temperature extremes throughout the year. Average ambient temperature over the year could be about 0°C, and the temperature can vary from -40°C to 30°C. The low ambient temperatures lead to an atypical power split between the propane compressor used for pre-cooling and the mixed refrigerant compressors used for liquefaction and sub-cooling. Typically the power split is 1/3 for pre-cooling and 2/3 for liquefaction and sub-cooling. At 0°C, this shifts to about 1/4 for pre-cooling and 3/4 for liquefaction and sub-cooling. Also, this power split can vary significantly due to the wide temperature extremes. There are several options for modifying the C3MR process in order to maximise the utilisation of power available from the compressor drivers while maintaining efficient and effective refrigerant compressor operation over the wide temperature range. One of these options consists of using a mixed refrigerant in the pre-cooling instead of propane. By varying the concentrations of the refrigerants used in the pre-cooling stage, plant operators can respond to changing climatic conditions. Increasing the proportion of propane creates a heavier mix in summer, while adding ethane yields a lighter mix for winter. The Dual Mixed Refrigerant (DMR) process has been developed to overcome the limitations imposed by the use of a single component refrigerant in the pre-cooling cycle. There are many variations of the DMR process, which use a mixed refrigerant for pre-cooling. This pre-cooling mixed refrigerant is heavier than the mixed refrigerant used for liquefaction and sub-cooling. The main advantage of these cycles is that the pre-cooling mixed refrigerant composition can be adjusted on a seasonal basis as the temperature changes. The DMR process provides the highest thermal efficiency, but also the greatest equipment count, complexity and multiple refrigerant handling. Traditional C3MR pre-cooling cannot be adjusted this way. However, around the equator in places like Brunei, Nigeria, or in Northern Australia, for example, temperatures vary less, so it makes sense to use propane first.
A student carelessly inserts the thermometer while assembling the calorimeter and a large hole is torn in the plastic lid. how will this affect his experimental results?
The results will be inaccurate due to the escape of heat. As the heat is created from the burning of the substance, it instead of being contained and measured (by the thermometer) some of that heat will escape through the hole in the lid, which will negatively impact the results.
Bleed 3800 engine cooling system?
Is the question how to bleed a Buick 3800 cooling system? I would say open that little petcock by the themostat housing and release all the air as you fill the system with coolant. When coolant comes out instead of air all the air is out.
Why do you pressurise a vehicle cooling system?
to increase the waters boiling point
Why you use sweet for coolant instead of salty coolant?
What ?????????????
Can you use water instead of or as a coolant if you do not have coolant?
Yes. The best to use is of course is a mixture of water and coolant but just water will work fine in your vehicle. Add coolant when you can get some for the best cooling. But only temporarily in an emergency. Water alone was fine (when the temperature stayed above freezing) back in the 1950s, but today's engines need the rust inhibitors and other additives.
Where is the radiator cap on your 93 Saturn sl1?
There is no cap on the radiator; instead, the coolant reservoir is pressurized along with the rest of the cooling system. Look on the passenger side, under the hood. You should see the windshield washer reservoir AND the coolant reservoir. Be careful with the lid of the coolant reservoir. If the engine is hot, it will blow off in your face.
How do you properly bleed cooling system on 1996 olds cutlass?
To bleed the cooling system on a 1996 Olds Cutlass, locate the bleed valve, which is on the front of the engine above the water pump. After making sure the cooling system is not under pressure, open the valve by turning it counterclockwise. Fill the radiator with coolant until no air comes out the bleed valve, and a stream of coolant begins to flow from there instead. Tighten the valve and close the system to finish the job.
What do you put in the cooling system of a 1993 ford explorer can you put water instead of coolant?
I would only put water in an emergency situation where I don't have coolant available. The coolant helps the engine to not overheat and to not freezing, while that could happen if you just use water. If you don't have your vehicle's manual to know the specification of the coolant, you can use the generally available Prestone and add water according to the table on the coolant's recipient. (or you can buy the pre-mixed formula)
Why use engine coolant instead of water?
Engine coolant is formulated to withstand a greater range of temperatures. Not only will it prevent freezing, but in hot weather it raises the boiling point to about 260° F, where pure water would boil at 212° F. The cooling properties are better and it doesn't rust or cause rust.
What type of coolant doses the Ford Escape use?
Most 2003 Escapes will have the yellow 5year/100,000 mile coolant(instead of the green 3 year/50,000 mile). (from http://www.escape-central.com/2003_Ford_Escape.htm) CAUTION: Vehicle cooling systems are filled with Motorcraft Premium Gold Engine. Coolant VC-7-A (in Oregon VC-7-B) or equivalent meeting Ford specification WSS-M97B51-A1 (yellow color). Always fill the cooling system with the same coolant that is present in the system. Do not mix coolant types. (from "General Procedures 303-03-2" http://www.justanswer.com/uploads/kennyz1963/2008-04-26_082220_cooling.pdf)
What is summer cooling affect?
The summer cooling effect is when the summer cools an area down instead of making it hot.
Would using water instead of coolant cause engine to over heat?
Water is coolant!!! Pre mixed coolant comes with anti freeze and sometimes a rust inhibitor, other than that it does same job. Common sense being your guide. Do not use straight water during the winter. Varying ratios of water mixed to antifreeze will actually increase the boiling point in both winter and summer and is more benficial in summer in terms of cooling function. More Coolant/antifreeze less water (mixed) increases boiling point correspondingly. It is of greater benfit to use coolant/antifreeze in your engine because it prevents rust and corrosion in the various parts of cooling system and heating system (heater) and increases the boiling point. Check the coolant/antifreeze container for instructions on mixtures and learn from it.
Will a car overheat without core plug?
yes a core plug is a metal disc in the engine block about the size of a 50p coin these are meant to be a weak spot in the cooling jacket of the engine and in theory will give way if the coolant freezes instead of cracking the engine block
