What is the temperature of water leaving a horizontal shell and tube condenser relative to the discharge gas?

• A. Equal to the discharge gas temperature
• B. A little cooler than the discharge gas
• C. A little warmer than the discharge gas
• D. Much warmer than the discharge gas

Answer: (B)

In a shell and tube condenser, the primary function is to transfer heat from the discharge gas to the water in order to condense the gas into liquid. The condenser operates on the principle of heat exchange, where the hot discharge gas enters the condenser and releases its heat as it moves through the tubes. As the hot discharge gas transfers its heat to the water flowing outside the tubes, the water absorbs this heat, causing its temperature to rise. However, the water cannot reach the exact same temperature as the discharge gas because of the inherent thermal dynamics and efficiency of heat transfer. Thus, the temperature of the water leaving the condenser will be slightly lower than that of the discharge gas. This temperature differential is crucial for efficient operation; it ensures that the gas can adequately cool down and condense while maintaining effective heat transfer through the condenser system. Therefore, describing the water temperature as "a little cooler than the discharge gas" accurately reflects this process of heat transfer in the condenser.
