Lets calculate the Log mean Temperature difference on a heat exchanger. - LMTD

LMTD = ((Temp Hot Inlet - Temp Outlet Cold)  -  (Temp Outlet Hot - Temp Inlet Cold))  / LN ((Temp Hot Inlet - Temp Outlet Cold)  -  (Temp Outlet Hot - Temp Inlet Cold))

First step is to go search macro or a page that contains the relevant tags.

Right clicking and adding them to the basket

Once you have added the tags you need in this calculation. were ready to get started.
