Flow Through a Pipe: Modelica Model with Unequal Inlet-Outlet Areas

[polezero]

Hello guys,

I need to model a pipe in modelica. Now modelica has its own fluid library where i can find a model of a pipe. But i need to model a pipe which has unequal inlet and outlet area. The outlet of the pipe is smaller than the inlet. Since mass going in the pipe=mass going out, hence the velocity of the fluid at the outlet should increase. I need a detail mathematical expression of this behavior. Please help me out.

You might want to be a little more descriptive.

Bernoulli with loss terms included for frictional/viscous effects? Seems pretty cut and dry.
