What size water pipe should you have to keep the pressure and volume the same as the water mains' to run 300' with a 30' rise?

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.

How can the hot water be at a higher pressure than the cold mains in an unvented system?
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.
Does volume affect water pressure?
Yes, volume can affect water pressure. In a closed system, an increase in volume typically leads to a decrease in pressure, and vice versa. This relationship is described by Boyle's Law.
When would the water mains pressure supplied to a premises be at its highest?
Call your city hall or Water Works for the information of what PSI it is set at.
Who is responsible for the water pressure coming in to a house?
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
What is the volume of 1 cu ft of water vapor at 1750 degrees F and atomspheric pressure when cooled to 100 degrees F?
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.
What is the average flow rate of water within a 32mm pipe at UK mains pressure?
30 litres per minute
How do you compute the volume of 100.0 kilograms of 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.
If you changed the water to water vapor in a pressure cooker what volume would the water vapor occupy?
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.
Your barn water hydrant has very little pressure how do you fix this?
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.
Why volume of water exerts greater pressure than volume of air?
Water is denser than air, meaning there are more water molecules in a given volume than air molecules. This greater density of water results in more molecules colliding with the surface, creating higher pressure. Additionally, water is less compressible than air, so changes in volume have a more pronounced impact on pressure.
Which direction do you turn the screw on the water pressure regulator to increase volume?
Screw in clockwise to increase pressure, has nothing to do with volume. Volume can only be increased by upsizing the pipe diameters. That's why it is called a pressure reg., not a volume reg.
Why is atmospheric pressure and water pressure different?
The big reason is because air is air, and water is water. The second reason is because air is compressible, while water cannot be compressed. What that means is that if you compress air to twice the pressure, it will be one-half the volume. If you compress water to be twice the pressure, the volume won't change.
