For example, dehumidifiers that are rated under 25 US pints (12 L) per day of water extraction receive an Energy Star rating if they have an energy factor of 1.2 (higher is better), while those rated 25 US pints (12 L) to 35 US pints (17 L) per day receive an Energy Star rating for an energy factor of 1.4 or higher.
Radon mixed with hydrogen entered the evacuated system through siphon A; mercury is shown in black. Radon was discovered in 1899 by Ernest Rutherford and Robert B.

The pressure vessel is a seamless cylinder normally made of cold-extruded aluminum or forged steel. [5] Filament wound composite cylinders are used in fire fighting breathing apparatus and oxygen first aid equipment because of their low weight, but are rarely used for diving, due to their high positive buoyancy.
