Cooling tower
Have you ever observed long,erected towers near any manufacturing plants and wondered what they are erected for ?
A cooling tower is a heat rejection mechanism which rejects excessive heat and cool the working fluid through the cooling of a water stream to a lower temperature. Cooling towers may either use the evaporation of water to remove process heat and cool the working fluid to near the wet-bulb air temperature and in the case of closed circuit dry cooling towers, air is used to cool the working fluid to near the dry–bulb air temperature.
Learning objectives
After completing the topic, the student will be able to:
Define and explore the concept of specific heat and its relevance to everyday science.
Calculate the amount of heat absorbed by a body and illustrate the significance of molar specific heat to the real world applications.
Explore the change of state of matter due to change in temperature
Investigate the process of evaporation, condensation, melting, freezing and relate their applications in daily life scenarios.
Explore about the concept of latent heat of a substance and distinguish from specific heat.
Explore and understand the difference between latent heat of fusion and latent heat of evaporation.
Analyze and illustrate the experiment of calorimeter and its types, to measure the amount of heat exchange.
