there is no size of pipe to keep the pressure the same if your rise is 30' and the volume or flow will drop with any size pipe too at 300' but if you want the least amount of pressure drop and flow for the smallest pipe to save costs then depending on demand I would run 3" or 4" solid core PVC or if you have pressure greater then 80 psi I would run 2" black poly if its for 2.5 bath or smaller home.
In a water pressure-volume diagram, the relationship between pressure and volume is inversely proportional. This means that as the volume of water decreases, the pressure increases, and vice versa.
In a closed system, the relationship between water pressure and volume is inversely proportional. This means that as the volume of water decreases, the pressure increases, and vice versa.
In an unvented system, hot water can be at a higher pressure than the cold mains due to the presence of a pressure-reducing valve on the cold water supply. This valve controls the pressure of the cold water coming into the system, allowing the pressure of the hot water, which is heated and stored at a higher temperature, to be higher. Additionally, the expansion vessel in the system helps regulate pressure fluctuations by absorbing excess pressure from heating water.
The relationship between water volume and pressure is inversely proportional. This means that as the volume of water increases, the pressure decreases, and vice versa. This is known as Boyle's Law, which states that the pressure of a gas (or liquid) is inversely related to its volume when temperature is held constant.
Yes, the more the water the greater the pressure of all the water pushing down on other water.
Call your city hall or Water Works for the information of what PSI it is set at.
the water company - if you look on their website it should tell you what the minimum water pressure you should expect is. You can test this by timing how long it takes to fill a certain size bucket. This is only cold water. The hot water pressure will depend on your boiler and should not be reported to the water company. There is more to this Yes the water company states what the min pressure should be in some cases as low as 8 PSI but before you start doing the bucket measurement one has to know the size of their pipe as each diameter will give a different flow rate and also what material your water main is as many ferrous mains do have a severe build up of mineral deposits which also affects flow rates . Also some mains do get "crushed" over the years if proper compacting is not used to insure the main is not bearing to much weight
Should this question be? = What is the volume of 1 cu ft of water vapor at 100 degrees F and atmospheric pressure? = It's initial volume doesn't matter as you only want to know what its final volume is.
The molar volume of liquid water at standard temperature and pressure is approximately 18.07 cm/mol.
30 litres per minute
Water vapor occupies about 1700 times more volume than liquid water. So, if you changed all the water in a pressure cooker to water vapor, the volume occupied by the water vapor would be about 1700 times the volume of the liquid water.
One kilogram of pure water at standard temperature and pressure has a volume of 1 liter. So if your temperature and pressure are standard and your water is pure, then the volume of 100.0 kilograms of it is 100.0 liters.
