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)
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.
Water would boil higher at the top of a mountain than at sea level. This is because there is less atmospheric pressure at higher elevations.

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.
negative pressure is needed for a sustained flow of water in a pipe.
depends on the pressure pushing through the pipe
the answer would be 48 m/s
Erosion / pipe bursting /pressure vessel failures
Water constantly exerts pressure on pipe joints. I have seen old soldered joints flying apart when subjected to extreme pressure or trains passing nearby. This sometimes happens with plastic pipe also if joints are not thoroughly set .
That would also depend on the length of the pipe, and on how fast you want the water to move. If you are in no hurry, even the slightest pressure will be enough to push the water through the pipe.That would also depend on the length of the pipe, and on how fast you want the water to move.
