Step 3. Use the calculation to solve a practical problem. An example would be a 150-foot measured water height in a municipal water tower. You would divide 150-feet by 2.31 to obtain the value of static pressure at ground level of about 65-psi.
Second, the circulating water flow rate has been calculated by balancing the pump's head against the hydraulic pressure drop through the tubes, the headers, and the piping of the condenser. In the second scenario, the flow rate reduces as the tube plugging increases and the tube-side pressure drop increases.
May 14, 2014· Remember, ASHRAE now assigns a maximum pipe size on cooling tower/condenser water systems. Include a fouling factor on pipes when sizing your pump. Open systems like cooling towers get dirty, so some degree of increased pressure drop is bound to occur with time. A 5 to 10 ft. safety factor is generally acceptable.
HVAC Wetside Design Package includes over (20) Programs and Forms that include hydronic pump head calculations (primary, secondary, and condenser water pumps), chilled water and heating water pipe sizing, and several additional HVAC design tools.
Calculate the pump discharge pressure from the pump total head To calculate the pressure at the bottom of a pool, you need to know the height of the water above you. It doesn't matter if it's a pool or a lake, the height is what determines how much fluid weight is above and therefore the pressure.
condenser water pump head calculation example for work,
Let's look at an example to demonstrate how to size a pump. 30000 kg/hr of water needs to be pumped from one vessel to another through the system shown in the diagram below. The water is at20C, has a density of998 kg/m3, a vapour pressure of0.023 bara and a viscosity of1cP. We'll assume that the pump efficiency is70%. Calculation. The calculation is presented below: Results. Pump flow rate …

Example plots are used to illustrate the effects of alternative modeling assumptions. Two models are used. The first is a submodel of a condenser and circulating water pump, along with supply and receiver reservoirs and associated piping. The second is a fossil steam turbine Rankine cycle that includes a condenser and circulating water pump. The method of calculation of the condenser's
Open Piping Circuit. For the tower piping circuit, the pump must overcome the piping flow friction loss; piping, condenser, cooling tower losses, and. valves. It must also provide the energy head necessary to raise water from a low to a higher static head level.
