UG-42 Multiple Opening
UG-42 Multiple Opening
(OP)
Hi dears
May anyone tell me the what means the below sentence mentioned in UG-42(a):
"No portion of the cross section is to be considered as applying to more than one opening, nor to be considered more than once in a combined area."
Thanks in advance.
