Question
Transcribed Image Text:**Problem 2: Heat Removal in a Condenser for Toluene Vapor**
A stream of toluene vapor (C₇H₈) is fed to a condenser at a flow rate of 6.5 mol/s. The initial conditions of the toluene are:
- **State Inlet:**
- Temperature (\(T\)): 50°C
- Pressure (\(P\)): 12.3 kPa
- State of Matter: Saturated Vapor
The vapor enters the condenser and exits as a liquid with the following conditions:
- **State Outlet:**
- Temperature (\(T\)): 25°C
- Pressure (\(P\)): 12.3 kPa
- State of Matter: Liquid
**Question:**
How much heat must be removed by the condenser to achieve this change of state?
**Diagram Explanation:**
The diagram illustrates the flow of toluene through a condenser. It displays:
- **Left Side (Input):**
- The toluene vapor enters the condenser from this side at 50°C and 12.3 kPa.
- **Condenser (Central Box):**
- This is the device responsible for removing heat from the vapor, causing it to condense into a liquid.
- **Right Side (Output):**
- The condensed toluene exits here as a liquid at 25°C while maintaining a pressure of 12.3 kPa.
This setup demonstrates the process of heat exchange in the condenser, focusing on the removal of heat to facilitate the phase change from vapor to liquid while maintaining constant pressure.
