Need Pressure Drop/Flow Calc Program.

I am looking for a program that can calculate the pressure drop and flow for a piping or ventilation system. Some of the key features I am looking for are:
1. Database with information on components (tees, elbows, valves, etc...) that can be added to
2. Database with common fluids
3. P&ID appearance
4. Export and import function from CAD software
5. Capable of generating reports on system

Have looked at Cranes, PipeFlow, and some others. Any suggestions?

Try

http://www.aft.com.

I use their Fathom software with great success. It won't import/export with CAD, but it has the schematic interface.
For CAD import/export try WaterCad by

http://www.haestad.com.

It will do most of what Fathom does and with a CAD interface.

PIPENET software from Sunrise systems has delivered good value for me; it is for both incompressible or compressible flow in pipes, ducts, etc

Good luck..

flowmaster is also a program to look at
