You can use flow rate and diameter calculator at:
http://www.pipeflowcalculations.com/flowrate/index.htm
where if you enter water velocity of 2 m/s and density of 1000 kg/m3 you can get pipe diameter.

Re: SEAWATER PIPES TRASPORT
I think that you can solve it easily with calculator at: http://www.pipeflowcalculations.com/pressuredrop/index.htm There you enter flow rate 2500 l/s and other inputs except pressure drop. Changing pipe diameter and calculating you will have different values for pressure drop. Once you get 1000 mmW...

Re: Converting pressure loss from Pipe Pressure Test ...
For your values I get velocity of 1.7 m/s which is ok for water, and it would be ok also if you are in the range of 2 m/s velocity.
More important is that the 4 psi pressure drop does not create cavitation and that there is sufficient pressure for the end user.

Re: Gas Flow through VERY small pipe
So you have another nozzle like one my image but in mirror on output? Diameters changes from 4 - 2 - 4 mm?downybear wrote: MD: In nozzle which I have in my hand right now D1 is 4 mm, D2 is 2 mm. Output to intake is 4 mm as well.
Input looks like on your image.

Re: Gas Flow through VERY small pipe
Here is the model that might give us results - it is the outlet nozzle: image - injector 2.jpg Now, pressure at pos. 1 is the pressure measured by "pressure sensor" and pressure at pos. 2 is the pressure on the "pressure sensor intake" - right? Diameter at pos. 1 and 2. are neede...

Re: Gas Flow through VERY small pipe
Can you tell me if the scheme on the top is good representation of the problem?

Re: Gas Flow through VERY small pipe
To be able to upload you have to put it in .jpeg or similar.
Here are images with my scheme for the problem.

Re: Flow rates in oil pipes
For laminar flow (Re<2300) flow rate will change with 4 power of diameter Q/Q1 = (D/D1)^4 For turbulent flow where friction factor is not depending on the Reynolds number flow rate will change with 2.5 power of diameter Q/Q1 = (D/D1)^2.5 Anyway, you can try with calculator at: http://www.pipeflowcal...

Re: Gas Flow through VERY small pipe
Some picture will tell more ... Regarding the pipe sizes,... All calculations in "basic" fluid dynamics are based on the assumption that fluid is continuous, which is actually not true, but if the diameter is big enough than you are OK. Big enough means that diameter is bigger than the fre...
