The typical working pressure of a nitrogen gas tank is around 15 MPa. This is the pressure under which the tank is designed to operate safely and efficiently. The internal pressure indicator for nitrogen tanks is usually set at 12.5 MPa.
[pdf] Any large volume of denatured fuel ethanol will typically be stored in conventional carbon steel storage tanks, such as those that are suitable for gasoline and other flammable fuels. Denatured fuel ethanol can also be stored in stainless steel storage tanks, although these tanks are less common.
[pdf] We can use dynamic mechanical analysis to measure the modulus of the material. Instead of continuously moving all the way through the linear elastic region, beyond which Hooke's law breaks down, we carefully keep the sample in the Hookean region for the entire experiment.
[pdf] Storage tank costs are tabulated in this data-file, averaging $100-300/m3 for storage systems of 10-10,000 m3 capacity. Costs are 2-10x higher for corrosive chemicals, cryogenic storage, or very large/small storage facilities.
[pdf] The working principle behind hydraulic accumulators involves compressing gas (typically nitrogen) to store energy. As system pressure rises, hydraulic fluid enters the accumulator, compressing the gas. When system pressure drops, the compressed gas expands, forcing fluid back into the system.
[pdf] Cleaning a fuel tank involves draining old gas, removing the tank, scrubbing out rust or debris, checking for damage, and reinstalling it with a new filter. DIY fuel tank cleaning saves money compared to professional service, but badly rusted or leaking tanks are better handled by a mechanic.
