The Energy Balance for Chemical Reactors - Rawlings Group

Work Term It is convenient to split the work term into three parts: W f, the work done by the ¯ow streams while moving material into and out of the reactor, W s, the shaft work being done by stirrers, compressors, etc., and W b, the work done when moving the system boundary.

Chapter 4 MATERIAL BALANCES AND APPLICATIONS

A material balance is an accounting for material. Thus, material balances are often compared to the balancing of current accounts. They are used in industry to calculate mass flow rates of different streams entering or leaving chemical or physical processes. 4.2. The General Balance Equation
