Convective Heat Exchange Due to Mass Flow

In continuous systems, the feed stream is not always at the same temperature as the reactor outlet. This temperature difference between the reactor feed (T0) and exit streams (Tf) results in a convective heat exchange with the surroundings. The heat flow is proportional to the heat capacity and the volume flow rate (i )  

This is an overall heat balance of a continuous reactor more detailed heat balances are introduced in Chapter 8.
