Conversion of liquid nitrogen cubes to tons
Thread Content
The existing liquid nitrogen tank has a capacity of 50 m3, and it stores liquid nitrogen at a pressure of 0.5 MPa. What is the equivalent amount in tons? Could someone expert help list the formulas? Thank you.
Approximately 730*50=36500KG
The tank with a capacity of 50 cubic meters doesn’t specify that it needs to be filled to capacity. It’s impossible to calculate without a liquid level; pressure values are useless. It’s not enough to simply have an unclear liquid level; the installation location of the level gauge and the dimensions of the storage tank also matter, as it’s necessary to know the relationship between the liquid level and the volume. Some liquid nitrogen tanks are equipped with gauges that can directly display the weight
How did this 730 come about? Could you give some guidance?
The density of liquid nitrogen multiplied by the volume. It’s its weight.
Does the density of liquid nitrogen change with pressure?
You can take a look at this post: https://bbs.hcbbs.com/thread-1372424-1-1.html
The pressure in the liquid nitrogen tank is around 10 kilograms; such a low pressure has a negligible effect on density. The density of liquid nitrogen is 800 kg/m3, and I’m not sure where the figure of 730 mentioned above comes from
