A recent question about flow along a conduit that changes shape....

This description seems like it would require you to setup a network
that included two sequential connections using the general conduit
component, in each one your would describe the hydrolic diam, roughness
and local loss coefficients.  Some transitions are listed in the duct  
design
handbooks as being equivalent to a local loss coefficient and if you
find one that is close to your situation then include that local loss
coefficient with one of the couduit components.
