Condensing plant: condensate temperature relative to cooling-water inlet In a surface condenser, compare the temperature of condensate leaving the condenser to that of the circulating water at inlet. Choose the correct relation.

Difficulty: Easy

Correct Answer: Higher than the cooling-water inlet temperature

Explanation:

Concept
Condensate in a surface condenser is approximately at the saturation temperature corresponding to condenser pressure (often ~30–45 °C under vacuum). The cooling water enters at a lower temperature and exits warmer after absorbing latent and sensible heat.

Therefore
At the outlet of the condenser, the condensate is hotter than the cooling-water inlet temperature.

Final Answer
Higher than the cooling-water inlet temperature
