For calculating the collapse pressure of a pipe, you first need to calculate the Hoop stress, which is given by :-
Stress = Circumferencial Force/(radial thickness*axial length)
If the stress crosses this value the pipe would collapse.
You would still need the coefficient of friction for the type of pipe in order to calculate flow.
Go to: http://www.techcalcs.com/calculators/pipeprop.php and use the calculator Otherwise calculate the volume displaced by the pipe and multiply by the density of the displaced water. This gives the bouyancy of the pipe
A Bourdon gauge consists of a C-shaped pipe with one end closed and the other end attached to a chamber whose pressure is being measured. When there is a pressure difference between the inside of the pipe and the outside, there will be a net force acting on the C-shaped pipe which will either try to curl the pipe into a tighter C shape (if the pressure in the pipe is less than the ambient air pressure), or the force will tend to straighten out the pipe (if the pressure is higher inside). This force can be measured, and from the measurement of this force, the gauge pressure within the pipe can be calculated.
The CFM of the equipment are given, how to calculate Static Pressure for it.
Test pressure
I want to know based on flow and pressure how to calculate diameter of the pipe
You would still need the coefficient of friction for the type of pipe in order to calculate flow.
t = PxDxA/2E where, t = thickness P = pressure D = pipe Diameter A = factor of safety E = tensile strength of pipe
You'll need the length of the pipe, because that's where the flow resistance is. At the outlet end, the pressure is atmospheric.
0.2 x(dia of pipe)x(length of pipe) For examble if you have 100mm diameter pipe and 50 m length .. 0.2x0.1x50= 1 litre and this is your allowable value
Insufficient information, one needs to know the pressure of the water entering the pipe, the relative heights of both ends the pipe, the pressure of the water at the discharge of the pipe, the geometry of the pipe including the number and types of turns, and the pipe material or internal friction coefficient. Then you can calculate the flow.
Its d schedule rating of pressure of pipe...
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
Under pressure, molecules are forced to move closer together, increasing their density. This can lead to changes in the physical properties of the substance, such as a decrease in volume or an increase in boiling point. In extreme cases, pressure can cause molecules to undergo a phase transition, changing from one state of matter to another.
Pressure Pipe Inspection Company was created in 1997.
for ex; design pressure in pipe 100bar,and what is test pressure in pipe
Your question has an error, the pressure increases as area of pipe decreases or the pressure decreases as the area of pipe increases. Answer: Conservation of energy
