How much is the boiling point of coolant per one pound of pressure?

From the following website. http://www.evanscooling.com/articles/aug98oc.htm Modern cars, like many of those built after 1955, started using pressurized cooling systems. The benefit was that, for every pound of pressure created in the cooling system, the boiling point of the water was raised by three degrees. By sealing up the cooling system, and adding pressure, the boiling point of the water was raised. Then, the engine could be operated at a higher temperature and operated more efficiently. Today, most modern cars use a 16-lb. cap to raise the boiling point 48 degrees higher than the normal 212 degree boiling point.

What could cause a '94 Olds Achieva S v6 to run hot within 15-30 mins of driving?
Cars can not run on just water because water boils at 212 degrees, no matter what. When coolant is mixed with water 50%-50%, the boiling point gets higher. Now,for every pound of pressure this mixture is put under, the boiling point will increase 3 or 4 degrees. So a 15 pound radiator cap can mean a possible 50-60 degree added to the boiling point. Now, a defective cap can decrease your boiling point.Thus a bad cap could be your problem
How do you recharge the AC in a 1996 Pontiac Grand Am when you can't find valve - except one that says something about a 1-pound pressure limit?
get under the car, its about 6 inches from the compressor with a blue cap (large line)
How many grams have a half pound of weed?
1/2 pound = about 226.8 grams.
What do mean by pound for pound boxer?
pound for pound is a way of saying without the obvious weight differance, is this guy who's 140lbs a better fighter than this guy who's 240lbs, it's who would win hypothetically if weight didn't matter. so the best pound for pound fighter would be simply the best, even though he'd lose to someone because of size.
What would cause oil in coolant reservoir on a ford 6.0ltr?
if you have oil in the reservoir then you have it in the radiator also, need to have it check for cracked or warped head and gaskett, also may be internal in the engine also. do a compression check on each cly. and see if there is more then a 10 pound differance, if so then need to take it to your local repair shop this is not a do it yourself job
A 10 psi radiator cap will raise the boiling point of coolant how degrees Fahrenheit?
the boiling point of the water will raise 3 deg. frht. for every pound of pressure the cap is rated for. a 10lb. cap will raise the boiling temp to 242deg. frht.
What would cause pressure on both radiator hoses?
The coolant system has to be under pressure to operate properly. For each pound of pressure the system is able to go 3 degrees above boiling point. Lets use water and water only for this example. Water boils at 212 degrees, if you have a 15 pound radiator cap then you can raise the temperature of the water to 257 degrees. 15 pound cap X 3 degrees per pound equals 45 degrees and add that to the boiling point of 212 degrees. With coolant, the numbers are slightly higher. You can't have pressure on one hose and not the other. It is a closed loop system. So if you have engine with 180 degree thermostat, that is too close to boiling point. Adding the 15 pound cap moves the boiling point to 257 degrees that way you have room to move the temperature up. It is similar to a pressure cooker.
Why does water boil in your reservoir?
Because it's very very hot. OR Is the correct temperature and has not enough pressure upon it to raise it's boiling point. Water's boiling point increases 3 degrees per pound of pressure upon it.
What is the effect of pressure on boiling point of butane?
If nonsalt water is placed in a closed system (for example an automotive cooling system) then for every pound of pressure the system can handle (ex. radiator cap) the boiling point of water (normally being 212f) is raised by 3 degrees. Thus, if said system can handle only 1 pound pressure before the water boils the temperature of the water when it boils should be 215F. Or so I understand.

Why does a 1996 firebird over heat?
Many reasons, we need more info. Cold be a stuck closed thermostat, plugged radiator, computer setting timing too retarded, improperly set distributer, lean fuel mix , injectors low pressure causing lean condition, cooling system blockage, one of the mose common is a bad radiator cap. Your cap should be tested and it must hold pressure. If it does not hold pressure, your boiling point of the coolant will be lower. For every pound of pressure you have, it raises the boiling point 15 deg. F. Do not use pure coolant, use only the recommended mix, usually 50/50 coolant/water. Using pure coolant will not protect more, it portects less. If these is a leak in one of the hoses, that will not allow presure also and could overheat. But then you'd see the leak on the ground. Could be a head gasket blown, allowing coolant to get to the cylinders . So, you see, you really need to do some basic checks first, check that cap. Good luck!
Would a 15 pound radiator cap make a difference from a 14 pound cap?
It will raise your boiling point very slightly, maybe 2 or 3 degrees.
Does more salt make water boil faster?
Short answer: no, it actually makes it boil slower. Dissolving salt to water lowers its melting point and raises its boiling point by an amount proportionate to moles of salt over kilograms of water. Adding 1.00 pound of salt to 1.00 kg of water raises its boiling point by 7.95 degrees C or 14.3 degrees F
Break in a lacrosse net?
Use lotion on it and pound it and pound after that put the net in boiling(hot) water and then pound it some more....just keep repeating that and it should work
What is a pound of air?
A pound of air is NOT a measure of pressure. A unit of pressure would be a weight ( a force really) for instance pound by a surface (square inch for instance). Pound is a unit of weight only. At sea level on earth barometric pressure, 1 cubic metre weighs 1.2kg (or 2.64 pound). Which means 1 pound of air represents a volume of 0.379 cubic metre of air. This obviously varies with atmospheric pressure (the air pressure) and the gravitional pull. a pound of air would represent a much bigger (6 times bigger roughly) volume on the moon for instance.
How many pound of pressure does a 80 pound person make when falling?
it depends how far they are falling
Why covelent com pound have high melting and high boiling point?
Covalent compounds have low melting and boiling points compared to ionics, because they have a weaker bond. They are only sharing electrons rather than completely giving or taking them, so they are not as strongly bonded, therefore they do not need as much thermal energy to break their bonds.
