Using FTEM to Recalculate the Temperature of a Stream in METSIM

FTEM is a mathematical function which calculates a stream temperarure from the heat content and the heat capacity.

Combining streams involves combining masses and heat contents of the components.  All of the heat will (in nature) and must (in mathematical simulations of nature) then be distributed based on the heat capcities of the components so that all components share one temperature - the final stream temperature.

The function FTEM enables you to calculate the stream temperature when you have made a change (such as using FADD) that may require it.
