Cooling Tower Pump Head Calculation

In this article explained about basic concepts of cooling tower types of cooling towers formula for cooling tower efficiency.

Cooling tower pump head calculation.

We ll assume that the pump efficiency is70. The most common open system is the cooling tower portion of a chilled water system as depicted below. Pump flow rate 30 m3 hr. Cooling tower efficiency calculation.

Keep in mind that you need the pump to develop enough pressure to get water to the highest and farthest places in the plant. 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. Pump total differential head 134 8 m. The calculation is presented below.

Net positive suction head available 22 13 m. For the tower piping circuit the pump must overcome the piping flow friction loss. The water is at20c has a density of998 kg m3 a vapour pressure of0 023 bara and a viscosity of1cp. A break in the piping system occurs where the water exits the spray nozzles and is exposed to.

In the ideal case the cold water temperature will be equal to the wet bulb temperature. Also brief about cooling tower mass balance of make up water requirement in system drift losses or windage evaporation losses blowdown or draw off. Some fairly catastrophic events can occur if either is improperly installed. Pump head is the total resistance that a pump must overcome.

Correctly piping the suction and discharge of your cooling tower condenser water pump is critical. Piping condenser cooling tower losses and valves. This is practically not possible to achieve. If you don t size the pressure drop right it won t get there.

Sizing the tower water pump can be a challenge too. Starting with the suction piping it is important to take precaution to avoid air pockets which can destroy a pump in pretty short order. The pump head calculation depends on the type of system that the pump serves. 526 charlotte avenue burkburnett tx 76354.

Cooling tower efficiency is limited by the ambient wet bulb temperature. The calculation of cooling tower efficiency involves the range and approach of the cooling tower. Pumps are typically sized for 65 feet of head.
