For every vertical foot of pipe, take that and multiply it by .434.This equation will get within 1/2 -1/4 psi.
you have first to know the thermal conductivity of PPR that you are dealing with. normally, this is in range between 0.1 to 0.24 W/MK .then you apply this formula Q(IN WATTS) =Thermal Conductivity/MK)*A( surface area for the pipe M2 )temperature difference between fluid inside pipe and temprture of pipe surface K)/(thickness of the pipe M)
To determine how many gallons will flow through a 2-inch copper pipe at a specific psi, you need to consider factors such as the pressure (psi), the length of the pipe, and any fittings or obstructions. Generally, a 2-inch copper pipe can flow approximately 1,200 gallons per minute at 50 psi under ideal conditions. However, for a precise calculation, it's best to use flow rate formulas or consult hydraulic tables that account for the specific conditions of your system.
The purpose is because the water pressure hydrauls the water and causes it to multiply to the power, therefore it makes the water stronger, making it easier to turn off the fire

The open channel flow has a free surface whereas the pipe flow has a closed surface.

When the pump is not running, the water pressure at the output pipe of the pump will be equal to the static pressure of the water source acting on the pipe. This static pressure varies depending on the elevation and depth of the water source.
If water is flowing through pipe, no head pressure can build up. Blocking off flow of water will create head pressure in pipe as long as pipe is vertical. A vertical column of water creates head pressure.
Yes, as long as the water coming out of the pipe has a greater pressure than the water that is covering the pipe. If it is the other way around, the water covering the pipe will actually flow into the pipe. Think about it. It just makes sense.
The pressure will rise, but you haven't given us anyvolume or pressure figures to begin with .
negative pressure is needed for a sustained flow of water in a pipe.
A pressure difference between two points along the pipe is necessary for the sustained flow of water. This pressure difference creates a driving force that pushes the water through the pipe, overcoming frictional resistance and allowing for continuous flow.
The water in your pipes is under pressure so that it comes out of the tap when you turn it on. If there is a hole in the pipe (i.e. a leak) then the water will come out under pressure, the same as if you turned on your tap - if this hole faces upwards then there will be a jet or water like a fountain. The height of this jet is dependant upon the pressure of the water
depends on the pressure pushing through the pipe
the answer would be 48 m/s
Erosion / pipe bursting /pressure vessel failures
