• Cooling Tower Factors: Temperature, Range Approach

     · For example, a designed tower may be guaranteed to cool 10,000 gpm of water from 95°F to 80°F at 75°F wet bulb temperature. In this case, the range is 15°F and the approach is 5°F. These design calculations are always done using average wet bulb temperatures at the site where the tower will be installed to ensure performance guarantees are met.

  • Reliability Analysis applied on centrifugal pumps

    The pumps system is composed by two centrifugal pumps disposed in parallel, one pump is operating and the other pump is waiting to be demanded. The system for the reliability analysis is called "Standby redundancy" type 1 of 2, just one pump is in operating mode and the other pump is waiting for failure of the first pump.

     · It is best to achieve the desired flow with as small a pump as possible and flow paths with minimum flow resistance. The bigger the pump, the more heat is added to the system. Eheim makes a 50watt unit that I see talked about every now and then. This guy is probably a bigger heat load on the cooling system than the CPU itself. Bottom Line

  • Water cooling

    Water cooling is a method of heat removal from components and industrial equipment. Evaporative cooling using water is often more efficient than air is inexpensive and nontoxic; however, it can contain impurities and cause corrosion. Water cooling is commonly used for cooling automobile internal combustion engines and power stations.

  • Considering NPSH When Making a Pump Selection | Intro to Pumps

    They key to making a good pump selection with regard to NPSH is to make sure you have all of the information before making a pump selection. Do not attempt to make a pump selection without know what the suction conditions are and the NPSHa that will be available to the pump during all operating conditions.

  • Water Cooling Flow Rate and Heat Transfer

     · Lowering the average water temperature, as we did above by increasing the flow rate, means we have a little better heat transfer from the CPU to the now somewhat cooler water. The result is that the CPU runs a little cooler. This all says that if you increase the flow rate and everything else remains constant, you will decrease the CPU temperature.
