What is formula for pressure at known water flow and pipe diameter?

There isn't one. Pressure in a piping system will be determined by the pump, or head of water if it is a gravity feed system.

One column of water has twice the diameter as another column of water. If the pressure is the same at the bottom of each column. How do the heights of the two columns compare?
The column with the smallest diameter has greater pressure and the column with a larger diameter has less pressure.
How much does pressure does a one half inch diameter column of water exert at its base?
The diameter of the water column does not affect the pressure.It is the height of the column that determines the pressure at the base.(and also the barometric pressure and temperature).
Can you calculate pipe diameter if you have pressure head and discharge flow?
Static pressure is .434 X height Example 10 ft x .434 4.34 PSI to prove take 2.31 PSI x 4.34 To find FORCE to need to calculate the diameter of the piping and the height and then the weight of the water inside the pipe
Does decreasing pipe diameter increase water pressure?
No. Pascal's Principle states that a pressure applied to a fluid system at rest is felt throughout the entire system. This means that, regardless of pipe diameter, city pressure is felt everywhere. Decreasing pipe diameter will only reduce the flow rate of the water, due to more head loss when the water moves.
What formula to measure pressure in a water tank?
Forget formula - put a gauge on it and read it.
What happens to speed of water in a pipe if the diameter of the pipe is decreased?
Assuming that the pressure remains at a constant, reducing the diameter of the pipe will increase the water flow. On the contrary, increasing the diameter would cause the water to flow at a much slower rate.
Does the diameter of a hose effect THE SPEED of water in a siphon?
No it does not, siphonage is due to inbalanced pressure or incorrect atmospheric pressure in a geyser
What is the formula for salt water buoyancy?
=pressure = Force/ Area=
You had a shower system that required 2.5 bar pressure to operate however the incoming pressure is only 2 bar max on a Dia50 nominal pipe how can you increase the pressure without pumps?
To increase the pressure you would have to reduce the diameter of the pipe. Half the diameter would give you twice as much pressure. Therefore to get 25 percent more pressure you would reduce the diameter by 25 percent giving you 37.5. Be careful though, this only increases the water pressure not the water flow rate.
What formula is used to find diameter when you know the circumference of a standard copper water pipe but not it's thickness?
Circumference divided by pi equals diameter. Pi X Diameter=Circumference.
How does the diameter of a column of water affect the pressure at the bottom of the column?
Yes and no, provided the pressure is kept constant, what appears to be more pressure is actually more volume. it appears to be more pressure, but it is an optical illusion, put a pressure gauge and be amazed.
What is the usual diameter for main water supply in residential setting?
That totally depends on how many houses there are, and what the pressure in the water mains is. The smallest allowed where I work is an 8" diameter water main, but 10" and 12" are common, too.
