Converting Volume Flow Rate into Volume

There's not enough information here.

Appears to be air (or other gas) flowing). If you know what retention time in the vessel is needed you could work it out. But you'd need to be clear whether it was actual retention time (at the pressure and temp) or nominal based on standard flowrate.

Retention time is not usually the design basis for a vessel, but I suppose it could be if it's a chemical reaction vessel for instance.

for what type of fluids this vessel used (( water , oil, gas,)) determine us

Here is an idea.

The assumption is that you are trying to measure the volume of a storage tank or a vessel that can be blanked for the purpose of its calibration.

No matter what the length, you fill in the vessel with a known incompressible fluid (usually water with corrosion inhibitor). You meter the quantity of fluid you use to completely fill the vessel in and record P & T for volume correction. Viscosity and SG of water with corrosion inhibitor can be determined using suppliers' info and/or and densitometer.

To meter the quantity of fluid you can either use a master meter or a suitable scale with a gage ton (this is a calibrated volume device that weight one ton when filled with water).

Since it seems that the geometry is preventing you from a simple calculation the easiest way would be to determine in experimentally. If you know the volume flow rate entering the vessel, with the vessel empty measure the time it takes to fill the vessel. Multiply that by your entering volume flowrate and you got it. Depending upon where the vessel's entrance is (top or bottom) could affect the accuracy of this method. i.e if filled toward the bottom, as the fluid rises above the entrace this will increase the pressure at the inlet thus affecting the flowrate. However the effect can be neglected dependant on certain applications.

A flow rate in m^3 / s divided by a velocity (m/s) provides an area of flow in m^2.

Pressure and temperature have no impact provided they don't change. You say you want to calculate the volume of the vessel but provide nothing else but a flow rate.

If that flow rate you provided is the rate at which you want to fill the tank, then we need a time in which you want to have the tank full, then we can calculate.

A volume is flow rate times time = m^3 /s * s = m^3.

So, what is it you are after?

Good day all,

I have a similar query but in more general sense. I searched a lot on google but didnt find the steps taken to finalize the dia lenght and configration of vessel.

I have an inlet separator whose dia is 3500mm lenght is 15m and its horizontal with ellipsoidal heads. some other information is also given in the datasheet. What I am after is that how did they came up with this size they could go for different combinations to end up at the same volume why did they selected these values??

Or if you just briefly explain the way of reaching to this level?

I couldnt find this on internet. If you explain this it will really be a contribution.

Thanks
