Identify the res present of the process of cooling
Answers
Answer:
Water cooling is a method of heat removal from components and industrial equipment. Water may be a more efficient heat transfer fluid where air cooling is ineffective. In most occupied climates water offers the thermal conductivity advantages of a liquid with unusually high specific heat capacity and the option of evaporative cooling. Low cost often allows rejection as waste after a single use, but recycling coolant loops may be pressurized to eliminate evaporative loss and offer greater portability and improved cleanliness. Unpressurized recycling coolant loops using evaporative cooling require a blowdown waste stream to remove impurities concentrated by evaporation. Disadvantages of water cooling systems include accelerated corrosion and maintenance requirements to prevent heat transfer reductions from biofouling or scale formation. Chemical additives to reduce these disadvantages may introduce toxicity to wastewater. Water cooling is commonly used for cooling automobile internal combustion engines and large industrial facilities such as nuclear and steam electric power plants, hydroelectric generators, petroleum refineries and chemical plants.[1] Other uses include cooling the barrels of machine guns, cooling of lubricant oil in pumps; for cooling purposes in heat exchangers; cooling products from tanks or columns; for cooling in HVAC in chillers, and recently, cooling of various major components inside high-end personal computers such as CPUs, GPUs, and motherboards. The main mechanism for water cooling is convective heat transfer.[2]

Cooling Water
Cooling water should be removed from all pump bearing brackets with dry-sump oil-mist lubrication, regardless of the pump product temperature.Cooling water from the cooling water system is frequently used to reject process heat in chemical industries. The performance of chemical processes could be greatly affected by varying conditions of cooling water. Therefore, there is a need of integration between chemical processes and cooling water system for effective use of cooling water and improve the performance of chemical processes. In this work, a nonlinear programming formulation is developed for operational optimization of integrated recirculating cooling water system and chemical processes. The model is solved to local optimality using CONOPT in GAMS. The results demonstrate the total profit can be significantly improved by 337 k£/y through integration compared to that without integration.
