A higher flow rate requires a larger pump. Pressure. The pressure at the inlet and outlet of the pump will determine the type and often the size of pump required. Knowing the pressure you are pumping against allows us to select the most suitable pump technology. If you are unsure of your differential pressure; we can help to calculate it.

This head is equal to the pump's lifting height (also called static head) plus the total head loss in the pipeline (including partial Head loss and head loss along the way). The formula for calculating the rated head of the pump is H=h+hj+hf. Among them: h——static head; hj——local head loss, hj=∑ζV^2/ (2g); hf——head loss along. Fire Pump Selection When the water supply doesn't have enough pressure, a fire pump can be an excellent solution to the problem, as long as the pump is sized correctly. ... (30 x 0.433) - (friction loss from water supply to pump) If we calculate the friction loss from the water supply to the pump as 5 psi, this becomes: PS at 900 gpm = 25.

Following are 16 steps for determining the proper boiler feedwater pump for a system: 1. Determine the control method to be used. Check the specification. 2. Calculate the base flow rate. Base flow rate is found using the formula: boiler maximum-capacity horsepower × 0.069 × C.

The spreadsheet is simple. You just input the data in dark yellow highlight. Pump sizing is calculated based on rated flow rate. If you want to size based on normal flow rate, input 0 in percentage of rated flow rate. Pressure drop components is comprehensive, including pipe loss, fitting loss, and equipment loss.

your system will need to operate efficiently. To determine that rate of flow you would calculate the boiler's output, rated in BTU (British Thermal Units) and divide that amount by 500 times the temperature drop of the water from the supply to return side of the boiler (usually 20°F), using this formula: GPM= BTU Output / (500 x Temp. Drop).

to be supplied by the pump if you want to achieve the required flow rate. In industrial systems, friction is not normally a large part of a pump's energy output. For typical systems, it is around 25% of the total. If it becomes much higher then you should examine the system to see if the pipes are too small. However all pump systems are.

This theory is applied in calculation of the NPSH of the pumps, which is shown in detail in this section.

TravisMack (Mechanical) 23 Jun 10 10:32. The use of 1000 gpm pump comes from the idea that a fire pump is required to perform at 65% of rated pressure while flowing 150% of rated capacity. Since a 1000 gpm pump can be used to get 1500 gpm, then you can go with the less expensive 1000 gpm pump. That does meet NFPA 20.
