Main Question or Discussion Point

Does anyone know how to calculate the mass of compressed hydrogen tank at certain pressure.

The tank is cylindrical with hemispherical ends.
I have pressure,radius,wall thickness and length,internal volume and density of the material.



The tank is a Type IV tank.(Composite tank with polymer liner.)Is it reasonable to assume that the polymer liner weight is neglible since it is a non-load bearing structure and just there to prevent hydrogen permeation.

Are there any formulas that calculate the weight of the tank valves and regulators and pumps as a factor of the tank weight.

Thanks for your help.

Since you know the material's density and have enough information to calculate the volume of the tank...just multiply the density times the volume to get the mass.
