From the Hangos and Cameron reference, (available here] - accessible from McMaster computers only)
- Work through example 2.4.1 on page 33
- Exercise A 2.1 and A 2.2 on page 37
- Exercise A 2.4: which controlling mechanisms would you consider?
Homework problem, similar to the case presented on slide 18, except
- Use two inlet streams \(\sf F_1\) and \(\sf F_2\), and assume they are volumetric flow rates
- An irreversible reaction occurs, \(\sf A + 3B \stackrel{r}{\rightarrow} 2C\)
- The reaction rate for A = \(\sf -r_A = -kC_\text{A} C_\text{B}^3\)
1. Derive the time-varying component mass balance for species B.
  - \( V\frac{dC_B}{dt} = F^{\rm in}_1 C^{\rm in}_{\sf B,1} + F^{\rm in}_2 C^{\rm in}_{\sf B,2} - F^{\rm out} C_{\sf B} + 0 - 3 kC_{\sf A} C_{\sf B}^3 V \)
2. What is the steady state value of \(\sf C_B\)? Can it be calculated without knowing the steady state value of \(\sf C_A\)?
  - \( F^{\rm in}_1 C^{\rm in}_{\sf B,1} + F^{\rm in}_2 C^{\rm in}_{\sf B,2} - F^{\rm out} \overline{C}_{\sf B} - 3 k \overline{C}_{\sf A} \overline{C}^3_{\sf B} V \) - we require the steady state value of \(C_{\sf A}\), denoted as \(\overline{C}_{\sf A}\), to calculate \(\overline{C}_{\sf B}\).
