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.
Pressure temperature relationship will tell you all you need to know
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.
Yes, the more the water the greater the pressure of all the water pushing down on other water.
When water freezes it increases in volume by %6. That pressure can destroy its' container.
DENSER MORE PRESSURE PRESSURE PRESSURE LOOK AT SCIENCE TEXT BOOK DONT CHEAT ON WIKI Water has more density than air.
30 litres per minute
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.
Turn up the mains pressure or replace your water lines if you have galvanised piping, the internal diameter might have been reduced due to rust.
Wet volume includes the vapor pressure of water, while dry volume does not.
The volume of the pressure cooker (unless it exploded).
