I am looking for some software that at the most basic level can calculate the pressure, temperature and pressure at different locations in a single phase system (H2O). The components located in the system are pumps, blowers, IC engines, different types of heat exchangers, valves, piping, ect.

This is not a real complicated system however it would be convienient to have some software where I can layout the system and do some "plug and play" type of changes with the components and piping.

Does anyone know of the availability of this type of software on the market?
