I know that current airlocks in space cannot be 100% efficient. There must be some loss in atmosphere or in the very least a certain amount of power consumption.
Can someone find statistics that detail:
1) the least amount of atmosphere lost by current airlock designs in operation in space.
2) The amount of power consumed in depressurizing the above airlock model.
3) The time it takes to depressurize and pressurize the airlock.
