what is considered normal water pressure (in PSI) in a traditional residential home in the US?
91692
In my neck of the woods, (Kentucky), the main water supply is approx. 70 psi from the city water co.  It is then reduced to approx. 45 psi. coming into the house.  This seems to be plenty of water, even when running the dishwasher while I am in the shower.

At least 3000 psi.  Recommend at least 180 degree water also.

Sounds like a job for Wikipedia!\n\nBlood pressure is the pressure of the blood on the walls of the blood vessels as the heart squirts it through the circulatory system.   When your blood first leaves the pump (your heart) it's moving as fast as it's going to, and there's as much pressure in the system as there's going to be.  The farther from the heart you go, the less the pressure in the system (just like an irrigation system, or the plumbing in a house.)\n\nThe heart not only has to pump the blood out to where it's needed, it has to pump it back again, to run it through the lungs to pick up some more oxygen so it can be recirculated.  Blood pressure is much lower on the return trip, when the blood is way out there far from the pump.  The outbound system is your arteries, the return trip is your veins.  \n\nMostly when you measure blood pressure, it's the pressure in the big arteries that are close to the skin and easy to find without poking any holes (the brachial artery in the arm is an example). \n\nThe traditional way to measure blood pressure is in millimetres of mercury (mm Hg), and you always state it the same way so everyone knows what you're talking about.  From a medical point of view what you're interested in is how much pressure there is in the system when the heart isn't squirting new blood into it (at the "resting" phase or "bottom" of the heartbeat cycle) which is called the diastolic pressure; and then how much pressure there is in the system at the top of the cycle, when your heart is forcing new blood into your arteries, which is called the systolic pressure.  So the "top of the cycle" number goes on top, and the "bottom of the cycle" number goes on the bottom.  A typical reading for a resting, healthy adult is around 120/80 (meaning 120 mmHg systolic and 80 mmHg diastolic)\n\nHope this is what you needed!

If the pressure is 0.76m of Hg, it is equivalent to 10.3 m of water. There is a vacuum in the tube above this water height.\n\nHowever, by “vacuum” we mean inside this space, the pressure is low. There will be vapour of water which will have some pressure.\n\nEven in mercury barometer, there will be mercury vapour inside the “Torricelli’s vacuum”.  \n\nThis is the reason that ordinary pump which sucks water from a well or sump is not able to lift water to a height more than 10m from the surface of the water.

For example, the density of water is 1000 kilograms per cubic meter (in SI units), so the weight of a cubic meter of water is 1000 kg times g, the acceleration of gravity (9.8 m/sec2), or 9800 newtons. This force is exerted over 1 m2, so the pressure produced by a 1-meter depth of water is 9800 pascals (the Pa is the SI unit of pressure, equal to 1 newton per square meter). \n\nThe unit of pressure used in atmospheric work on Earth is the hectopascal; 1 hPa = 100 Pa. So the pressure 1 m below the surface of water (ignoring the pressure exerted by the atmosphere on top of it) is 98 hPa. Standard atmospheric pressure is 1013.25 hPa, so it takes 1013.25/98 = 10.33 meters of water to produce a pressure of 1 atmosphere. (That's about 34 feet, for those who like obsolete units.) \n\nThe pressure in the ocean increases by about 1 atmosphere for every 10 meters of depth. The average depth of the ocean is about 4 km, so the pressure on the sea floor is about 400 atmospheres.

One way is to use the Clausius-Clayperon Equation.  See the link below and use the boiling point of water for one of the pressure and temperature pairs.  \n\nP.S.  It's equation 22 in the linked document.

It depends on the temperature of the fluid:\n-20°F to 100°F Max non shock pressure rating is 2160 psig\nat 850°F Max non-shock pressure rating is 900 psig

NTP - Normal Temperature and Pressure - is defined as air at 20oC (293.15 K, 68oF) and 1 atm ( 101.325 kN/m2, 101.325 kPa, 14.7 psia, 0 psig, 29.92 in Hg, 760 torr). Density 1.204 kg/m3 (0.075 pounds per cubic foot)

It is filled with air.  It has a circumference of 27-28 inches with a weight of 14-16 ounces.  It should have the air pressure of 8.5 to 15.6 PSI.

Are any of you educated in science?\n\nBernoulli's Principle states that as the speed of a moving fluid increases, the pressure within the fluid decreases. It has absolutely nothing whatsoever to do with air pressure and temperature. You're thinking of either Charles's Law or Boyle's Law, but again neither have any relevence here.\n\n\nHow possibly can hurricanes affect the water pressure in Latin American countries? Don't they get hurricanes in the US and does the US have a water pressure problem?\n\nWater pressure, the hotter the air (also water) the lower the pressure, thats why hurricanes form in the carribean region ( they need moist{sea} warm air)\n\n\n\nThe next answer is actually theoretically correct, you do weigh less at the equator than at the poles, but the effect is small (0.5% weight difference) and certainly doesn't have a significant effect on the plumbing in Latin America. This is equivalent in a 10 storey hotel to raising the roof storage tank by approximately 6inches or 15cms to negate this effect:\n\nWell pardner, my guess would be that centrifigal force at the equator is greater than at areas further north and further south. The ideal launch sites for stuff being flung out into space would be close to the equator for the same reason.\n\n\nThe real reason as any competent plumber will tell you is a combination of the head of water (the pressure the water is being fed with) and the diameter of the pipes, smaller pipes allowing less flow. The pressure of the water is dictated either by the water supply companies who pump the water at a certain pressure (Mains pressure) or if the system is being fed from a tank, it depends how high above the tap the water tank is. Higher tanks give higher pressure, which is why a shower on the ground floor fed from a tank in the loft gives a better flow than one on the top floor.\n\nBasically, they've got rubbish plumbing and it's being fed either at a lower pressure by the utility companies or they are using smaller diameter water pipes, all probably compounded by general drinking water shortages.

Each 1033.23 centimeters of fresh water adds 1 atmosphere of pressure.\n\nHere is why:\n\n1 atmosphere of pressure is equal to 14.696 pounds per square inch, which is the same as saying 1033.23 grams per square centimeter.\n\nEach CUBIC centimeter of water has a mass of 1 gram, because 1cm^3 = 1mL which is by definition 1g of pure water (and fresh water has little to no impurities).  That means a 1033.23-cm tall column of water 1cm by 1cm will have a mass of 1033.23 grams, all pressing down on 1 square cm area at the bottom -- that column will be exerting 1 atmosphere of pressure on the bottom area of 1 square centimeter.\n\nThe area at the bottom does not matter, since as you increase the AREA you increase the VOLUME (thus the MASS) by the same ratio as long as the water column stays the same height -- but it is easier to imagine based on a 1cm x 1cm column.\n\n1033.23 centimeters = 33.9 feet.\n\nSo what we need to do to solve your question, is figure out how much pressure IN ADDITION TO THE ATMOSPHEREIC PRESSURE, must be supplied by the water:\n\n3.5 atm - 0.9atm = 2.6 atm \n\n2.6 atm * 1033cm/atm = 2686.4 cm\n\nSo, at 2686.4 cm (26.864 meters, or 88.14 feet) the water will be adding 2.5 atmospheres of pressure to the 0.9 atmospheres pressure provided by the atmosphere itself, for a total of 3.5 atmospheres of pressure.\n\nBTW, there is a way to work it out without all the "american" units (feet and pounds, just using the metric unit of force which is a Newton) but I'm so used to doing it in "american" units that this way is quicker for me...

Exactly!! I have to boil water to take a bath. I do not have the luxury of a shower! I use gas for heat not central air and heat. I have to go out and turn on the water directly from underground so that I can fill it up in the tub. I also do dishes in the tub. I live in the United States doing this! I do not see myself as poor, but rich because my family is together and happy. I do not live like that and prefer not to because I like only having what I need to survive not a big house with lots of money. It is of no interest to me or concern. It is boring!! How is that for being against the normal American stereotype!! haahha!

hi chuck, \n\n5300 lbs of pressure?  yikes!  hate to be working near that thing if it should blow!\n\nanyway the point of a bladder accumulator is to expand/contract thereby absorbing transient fluctuations in the pressure, right?  so i would expect you would want it to be somewhere near the middle of its range - too empty and it won't be full enough to compensate for pressure dips, and too full and it won't be able to expand to handle pressure spikes.  so somewhere near halfway i.e. 60% sounds reasonable to me.  \n\nthis is one of those things where a calculation of the pressure depends on a LOT of weird variables like the elastic constant of the bladder, the shape of it etc.  your best bet to get maximum damping is probably to just do an empirical trial and error sort of thing.\n\n200 Hz is well within the audible range of the human ear.  G3 on the piano (find middle A, go down an octave plus one white key - that's low G) is supposed to be tuned to 196 Hz, so your 200 cps hum should sound almost like low G.  depending on the amplitude of the pulses you could probably just listen to the pipes, or use a stethoscope if it's too quiet, and then vary the charge pressure looking for a minimum in the hum.\n\ngood luck!
