Steam ejector or vacuum pump? The principle is energy conversion!

Vacuuming means reducing pressure; the pressure in a system in contact with the atmosphere is 1 atm. When the pressure within the system needs to be lower than 1 atm, a vacuum pump can be used to remove the gas from the sealed system, thereby achieving a reduction in pressure.
