10、 or a construction of one grain per hour,square foot, inch of mercury pressure difference.3.2.1.1 DiscussionIf a specification states that a one permlimit is required, the same flow rate will be obtained from thefollowing relationships:1 perm = 1 grain/h ft2in. Hg (inchpound)= 57.2 10;12kg/(Pasm2) (
