Cooling Tower Pump Head Calculation

This is practically not possible to achieve.

Cooling tower pump head calculation.

Piping condenser cooling tower losses and valves. In this article explained about basic concepts of cooling tower types of cooling towers formula for cooling tower efficiency. A break in the piping system occurs where the water exits the spray nozzles and is exposed to. Some fairly catastrophic events can occur if either is improperly installed.

526 charlotte avenue burkburnett tx 76354. Pump flow rate 30 m3 hr. The calculation is presented below. Pump total differential head 134 8 m.

Starting with the suction piping it is important to take precaution to avoid air pockets which can destroy a pump in pretty short order. In the ideal case the cold water temperature will be equal to the wet bulb temperature. 1 1 cooling tower a cooling tower is a specialized heat exchanger in which air and water are brought into direct contact with each other in order to reduce the water s temperature. The pump head calculation depends on the type of system that the pump serves.

It must also provide the energy head necessary to raise water from a low to a higher static head level. Pump head is the total resistance that a pump must overcome. Also brief about cooling tower mass balance of make up water requirement in system drift losses or windage evaporation losses blowdown or draw off. Correctly piping the suction and discharge of your cooling tower condenser water pump is critical.

Net positive suction head available 22 13 m. As this occurs a small volume of water is evaporated reducing the temperature of the water being circulated through the tower. Cooling tower efficiency calculation. Cooling tower efficiency is limited by the ambient wet bulb temperature.

We ll assume that the pump efficiency is70. If you don t size the pressure drop right it won t get there. Pump power 15 7 kw. Pumps are typically sized for 65 feet of head.

For the tower piping circuit the pump must overcome the piping flow friction loss. Keep in mind that you need the pump to develop enough pressure to get water to the highest and farthest places in the plant. The most common open system is the cooling tower portion of a chilled water system as depicted below.
