Convert m3/h to either psi or bar

Does anyone know if it's possible to convert from m3/h to either psi or bar. I'm trying to convert 1030 m3/h. Cheers

There is no direct conversion between flow rate and pressure. There is a relationship between them, but it would depend on too many other circumstances.

pls assist me in converting m3/h to psi

m3/h to either psi or bar.

There is no conversion of m3/hr to psi. Using the electrical analogy - m3/hr is a measure flow which in the electrical analogy is equivalent to current (Amps) whereas psi is a measure of pressure which is eqivalent to electrical potential (Volts). As we know these are related through the resistance of whatever is being supplied (Ohm's Law). The same applies here (is it a water network/problem) - they will be related depending on the resistance of the network being fed. The higher the pressure the higher the flow for a given network but it is not linear. Do Google search on Hardy Cross.

The tire on your car holds a certain volume of air at a certain pressure. It maintains that pressure precisely because there is no flow. If there is flow, the tire will go flat.

Over the length of a pipe, there is a pressure difference from one end to the other that is necessary to maintain flow by offsetting the flow resistance in the pipe. That is a very complex relationship that depends on what is flowing, how fast, the diameter and surface roughness of the pipe.

Which would those other factors be ? Need to convert 600 m3 of natural gas to bar.
