What is the ultimate system pressure in this case

Reference no: EM13681245

A system of volume equal to 1m^3 is evacuated to an ultimate pressure of 10^-7 torr employing a 200liters/s pump. For a reactive evaporation process, 100cm^3 of gas (STP) should be continuously delivered through the system per minute.

1. What is the ultimate system pressure in this case?

2. What conditions are necessary to maintain this process at 10^-3 torr?
