M=3, and all three mass flow rates of individual species are given, totally specifying this stream without the need for any unknowns associated with this stream. Alternatively, total flow rate and M-1 fractions can be picked. WebSep 24, 2024 · In the steady state, we can take \(dE/dt = 0\), and if the reactions are carried out adiabatically, which requires slow stirring and a low flow rate, then \(dQ/dt = 0\) as well. In this case, we can solve for the operational temperature \(T\), which gives in an industry with low margins
