What is the necessity of cooling tower?
Cooling towers are primarily used for heating, ventilation, and air conditioning (HVAC) and industrial purposes. Cooling towers provide a cost-effective and energy efficient operation of systems in need of cooling. More than 1,500 industrial facilities use large quantities of water to cool their plants 2.
What is the function of cooling tower in a power plant?
What is the function of a cooling tower in a power plant? Explanation: The cooling water that is passed through the condenser, for condensing steam coming out of the turbine, gets heated and in order to cool that water down, cooling towers are used. So that the water can be reused again.
What is the necessity of introducing second law of thermodynamics?
The Second Law of Thermodynamics is about the quality of energy. It states that as energy is transferred or transformed, more and more of it is wasted. The Second Law also states that there is a natural tendency of any isolated system to degenerate into a more disordered state.
What is the purpose of a cooling tower quizlet?
What is the purpose of the cooling tower in a water-cooled system? The cooling tower is the unit in a water-cooled system that rejects the heat into the atmoshere. Spreading the water out as it passes though the cooling tower helps the water —- faster.
What is the purpose of cooling tower in central AC plant Mcq?
The purpose of a cooling tower is Cooling tower is used to cool the hot water coming from condenser. This water is cooled by evaporating cooling by the flowing air.
What is the principle of cooling tower?
A cooling tower is a heat removal device that uses water to transfer process waste heat into the atmosphere. All cooling towers, including commercial & industrial cooling towers, operate on the principle of removing heat from water by evaporating a small portion of water that is recirculated through the unit.
What are the two important statements of Second Law of Thermodynamics?
We now present two statements of the Second Law of Thermodynamics, the first regarding a heat engine, and the second regarding a heat pump.
What is the importance of the laws of thermodynamics in the balance of ecosystems?
The use of the Second Law of Thermodynamics for open systems is crucial. Ecosystems violate the Second Law because they are moving away from thermodynamic equilibrium by formation of a biological structure. Ecosystems receive energy as solar radiation, which can compensate for the steady transfer of work to heat.
How do cooling towers prevent algae growth?
Algae in your cooling tower is best prevented by:
- Cleaning your cooling towers regularly, according to your manufacturer directions.
- Developing and following an effective water management plan, which will outline when your cooling tower may be in need of extra cleaning.
What is a cooling tower plume?
Cooling tower plumes form when water vapor generated in the cooling tower mixes with the colder ambient air as it leaves the tower and condenses. The plume, sometimes called white smoke, consists of small droplets of water that are suspended in the air, similar to fog. …
How is performance of the cooling tower indicated?
How is the performance of the cooling tower indicated? Explanation: Approach can be defined as the temperature difference between water leaving the cooling tower and ambient wet-bulb temperature. If the approach is low, then the performance is good and vice-versa.
What is the purpose of eliminator in cooling tower Mcq?
REDUCE WATER LOSS AND EMISSIONS In all different types of cooling towers drift eliminators are used to reduce the loss of water and emissions. Above the water distribution and the cooling fills, a layer of drift eliminators is installed for this purpose.
What is coolcooling tower?
Cooling towers are widely used in oil refineries, petrochemical plants, thermal power plants, nuclear plants, food processing plants, natural gas plants etc. Ever wondered how it works? The cooling towers are normally placed within the industries.
How do nuclear power plants cool the cooling tower?
Most nuclear power (and other thermal) plants with recirculating cooling are cooled by water in a condenser circuit with the hot water then going to a cooling tower. This may employ either natural draft (chimney effect) or mechanical draft using large fans (enabling a much lower profile but using power*).
How does a water cooling tower work?
The spray nozzles spray the hot water inside the tower. Air from the atmosphere comes in contact with the hot water, so that causing some water droplets to evaporate. Latent heat gains by the evaporated water droplets from the surrounding water, which causes the remaining water to cool.
What is the difference between mechanical and natural cooling towers?
Mechanical-draft cooling towers. Mechanical-draft cooling towers use either single or multiple fans to provide a known volume of air through the cooling tower. Therefore, their thermal performance is generally more stable and is affected by fewer air variables than with natural draft cooling towers.
