[TRNSYS-users] Pressure drop calculation in pipe, duct and heat exchanger

[mahdi shahrestani]

Hello every body 
 
After review of some components inputs and outputs I found that pressure drop calculation is not included in many models like pipes, ducts and heat exchanger.
 
I was wondering if any body could help me and give me a clue to find a way to calculation of pressure drop of these components in TRNSYS.
