Want this question answered?
well chilled water temperature is below 40C but higher than 00C. where as cold water which we get from cooling tower is usually about 200C to 360C but below our body temperature.
I believe you mean the temperature at which water vapor condenses due to cooling. This is the dew point temperature.
A certain amount of the energy carried by the cooling water, is kinetic energy, from the circulation through the cooling system. When the engine is turned off, the water stops circulating. The kinetic energy contained in the water is converted to heat, thus raising the temperature of the coolant.
Engine temperature rising when the engine is idling is normal. The car is sitting still and no air is entering the engine compartment. This will cause the engine temperature to rise. The cooling fans then come on and the engine returns to a normal temperature. Unless the cooling fans do not bring the temperature down, you have no problems and this is totally normal.
This depends on the temperature.
Water temperature from cooling tower outlet will be well below the dew point of the ambient air. Dew point is the temperature at which a portion of water in air (termed as humidity) condenses at constant barometric pressure. Higher humidity means the water return temperature will be higher.
The Approach is the difference between wet bulb temperature and outlet water temperature from cooling tower. That means , in this case, Approach = 35-25=10 degrees.
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 fromcooling water. The make-up water source is used to replenish water lost to evaporation. Hot water fromheat exchangers is sent to the cooling tower. The water exits the cooling tower and is sent back to the exchangers or to other units for further cooling. Cooled water is needed for, for example, air conditioners, manufacturing processes or power generation. A cooling tower is an equipment usedto reduce the temperature of a water stream by extracting heat from water and emitting it tothe atmosphere. Cooling towers make use of evaporation whereby some of the water is evaporated into a moving air stream and subsequently discharged into the atmosphere. As a result, the remainder of the water is cooled down significantly (Figure 1). Cooling towers are able to lower the water temperatures more than devices that use only air to reject heat, like the radiator in a car, and are therefore more cost-effective and energy efficient.
Cooling load in kw is increase the temperature of the water before enter the cooling tower, thus the differential heat energy level is high compare to surrounding temp., so it will transfer heat more to surrounding and leave the tower with low temperature, and it will become more like to approach the wet bulb temp., this happens if the variables such the water flow, and the air velocity is kept constant.
Range is the difference of cooling water inlet and cooling water outlet temp

It Tries to bring down the hot water temperature to Wet Bulb temperature. Therefore does cooling. [ebolton] The refrigerant in the AC system picks up heat from the air conditioned space by turning it from liquid to vapor in the evaporator. Within the cooling tower, the refrigerant turns back to liquid in the condensor, releasing heat to the water in the tower, which itself evaporates releasing the heat to the atmosphere.[eboton]
It evaporates into the atmosphere using a cooling tower.
power plant
The Cooling tower is installed where the continuous heat rejection is required. Like process plants. Type is depends up on use & water property.
The only thing that I've heard of with "wet cooling" in, is a wet cooling tower. A Wet Cooling tower for the closed-circuit cooling of water where the water to be cooled comes into direct contact with the cooling air dissipating heat by evaporation and air heating. The air draught required for cooling can be induced by fans or by the natural effect of the stack of the cooling tower building (natural draught cooling tower).So I don't know if that answers your question or not, but i hope it helps...
