    • 20 Pages

    Abstract The phenomenon of evaporative cooling is a common process in nature‚ whose applications for cooling air are being used since the ancient years. In fact‚ it meets this objective with a low energy consumption‚ being compared to the primary energy consumption of other alternatives for cooling‚ as it is simply based in the phenomenon of reducing the air temperature by evaporating water on it. This process can be an interesting alternative to conventional systems in these applications where

    COOLING TOWER INTRODUCTION: Cooling towers are a very important part of many chemical plants. The primary task of a cooling tower is to reject heat into the atmosphere. They represent a relatively inexpensive and dependable means of removing low-grade heat from cooling water. The make-up water source is used to replenish water lost to evaporation. Hot water from heat exchangers is sent to the cooling tower. The water exits the cooling tower and is sent back to the exchangers or to other units

    Fresh Water Cooling System Introduction Although there is an abundance of free sea water available‚ marine diesel engines do not use it directly to keep the hottest parts of the engine cool. This is because of the corrosion which would be caused in the cooling water spaces‚ and the salts which would be deposited on the cooling surfaces interfering with the heat flow. Instead‚ the water circulated around the engine is fresh water which is then itself cooled using sea water. This fresh water is

    Cooling Drinks 1) What is the specific latent heat of fusion of water? Specific latent heat of fusion is the amount of heat absorbed or released by a substance when changing states. This could be boiling or melting. Latent heat of fusion is the amount of energy needed to melt a substance‚ while latent heat of vaporisation is the amount of energy needed to boil a substance. The specific latent heat of fusion of water is 334 j/g In the graph‚ you can see that as the temperature increases more
