Convective Heat Transport due to Feed

If a feed stream to a reactor is at a different temperature from the contents of the reactor, there is convective heat transport to the reactor. The thermal effect of the feed stream must be accounted for in the heat balance [Eq. (7)]. 

This effect is also called sensible heat . It can also be used as an additional means of cooling in semi-batch and in continuous reactors. When the temperature difference between reactor and feed is important and/or the feed rate is high, this term may play an important role. In such cases, when the feed is stopped an abrupt increase in the reactor temperature may result. This term is also important in calorimetric measurements, where the appropriate correction must be performed.
