After evacuation of a chamber whose volume is 30 L to a pressure of 1 x 10-6 torr, the pumps are isolated. The pressure rises to 1 x 10-5 torr in 3 min. a. What is the leakage rate? b. If a diffusion pump with an effective speed of 40 L/sec is attached to the chamber, what ultimate pressure can be expected?
