Cstr mass balance

WebWe note that since the reactor is being filled, the volume, V, varies with time. The reactor volume at any time t can be found from an overall mass balance of all species: For a … WebThe steady state mass balance equations maybe expressed by using the usual notation as follows ... [Pg.710] The mass balance of a continuous flow stirred-tank reactor (CSTR) with a first-order chemical reaction is very similar to the problem in Section 2.8.1 (p. 2-20). We just need to add the chemical reaction term.
