The CAESAR II User Guide (pg. 614) shows the formula for the APPLIED (static) load as rho*V^2*A*[2(1-cos(theta)]^0.5. This formula does not address the INDUCED load which may be DLF*(Applied Load).
The CAESAR II seminar notes had an incorrect listing for this magnitude.
With a little work, the formula in the User Guide matches that found in Kellogg's Design of Piping Systems page 285.
