A bypass pot feeder is used to add a chemical (liquid or solid) to the suction side of a process pump. This is most commonly used with cooling water that is circulated from a cooling water tower to a heat load. Injecting chemicals can be used to control pH or various bacteria, etc.
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.

It would have to be awful cold for an awful long time for a water tower to freeze solid. The water is typically moving most of the time as it flows in and out. Water being pumped into the tower is going to be above freezing. And the large mass of water makes it pretty hard to get that cold. In colder climates, they may even have some sort of heating device, it only has to keep the water above freezing. And I'm sure the top edges get some freezing around them. ASS yes it could, anything could happen!!!
It was a Stratovolcano, but the magma filled and cooled over a period of time and it hardend. The exterior eroded away and exposed the cooled magma, which is now today Devils Tower. It is classified as Extinct.
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...
The Cooling tower is installed where the continuous heat rejection is required. Like process plants. Type is depends up on use & water property.
There's quite multitude of things that impact a cooling performance. Specifically the height of the tower impacts on the the drafting air through the tower. See "Air Cooled Heat Exchangers and Cooling Towers" by Kroger for something more indepth.
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.
Range is the difference of cooling water inlet and cooling water outlet temp
It evaporates into the atmosphere using a cooling tower.

These are the large towers you will see at a coal fired power station amongst numerous other applications. e.g. In a coal fired power station, burning the coal heats water to produce steam which is in turn used to generate electricity. The water is usually taken directly from an adjacent river and then returned to the river. If the water was not cooled first then the temperature of the river water would rise and completely change the eco-system within. Therefore, the waste hot process water is passed through cooling towers. The shape of the cooling tower draws heat from the water, expelling it to the atmosphere before returning it to the river to minimise the rise in river temperature. See this web article for more information.... http://en.wikipedia.org/wiki/Cooling_tower
Typically this would involve standard titration and colourmetric techniques, which involves analysis and monitoring of the cooling tower.
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.
