Let's **solve the first question** step-by-step: --- ## 1. **Pressure Drop Across Packed Bed Reactor** The Ergun equation for pressure drop per unit length is: \[ \frac{dP}{dz} = -\frac{G}{\rho D_p} \left( \frac{1-\epsilon}{\epsilon^3} \right) \left[ \frac{150(1-\epsilon)\mu}{D_p} + 1.75G \right] \] But the question asks to **calculate the total pressure at the reactor exit** given: - Inlet pressure, \( P_{in} = 500 \) kPa - Bed length, \( L = 4.5 \) m - Average pressure gradient, \( \left| \frac{dP}{dz} \right| = 12.5 \) kPa/m --- ### **Step 1: Calculate Total Pressure Drop** \[ \Delta P = \left| \frac{dP}{dz} \right| \times L \] \[ \Delta P = 12.5 \ \text{kPa/m} \times 4.5 \ \text{m} = 56.25 \ \text{kPa} \] --- ### **Step 2: Calculate Exit Pressure** \[ P_{exit} = P_{in} - \Delta P \] \[ P_{exit} = 500 \ \text{kPa} - 56.25 \ \text{kPa} = 443.75 \ \text{kPa} \] --- ## **Final Answer** \[ \boxed{P_{exit} = 443.75 \ \text{kPa}} \] --- ### **Explanation** - The pressure drop across the bed is the product of the pressure gradient and the bed length. - Subtract this pressure drop from the inlet pressure to get the pressure at the exit. --- Let me know if you want step-by-step solutions for the next parts!
