Wind acc. UBC 97

Dear Dave, Dear Richard, Hello Pipers,

Does anybody know, what is the real correct "Pressure Coefficient Cq" acc. UBC 97, Table-16-H for piping elements ? I would assume 0,8.
Is it the same factor as the Caesar "Wind Shape Factor" or a different one, in other words, would in be double to calculate with Cq and the WSF, normally 0,7 ?

Thanks in advance and Regards
Peter
