In the old manual of plant i have studied the flare load calulation, the total load has been determined i.e 19,70,000 lb/hr on the basis of electrical power failure case.the vendor used Regular adjustment factor of 75 % and then calulate the new load i.e

0.75* 19,70,000 = 14,77,500. so My question is,

 

1.What is Regular adjustment factor ? and why we use this ?

2.If relief load has been increased then how the adequacy of flare stack and piping would be checked? BY calculating Mach no on new conditions keeping in view the criteria of 0.5 mach no.?or any other criteria as well ?

3.Is the same 0.5 Match no criteria is used for flare header and flare stack?
