Calculate pump power
Thread Content
A centrifugal pump is used to transfer the raw material from the storage tank into the tower; the pressure inside the tower is 295 KPA (gauge pressure). The liquid level in the storage tank is maintained at a constant level, at atmospheric pressure. The vertical distance between the storage tank and the tower inlet is 20 meters. The flow rate is 12 M3/H, the density of the material is 900 KG/M3, the diameter of the pipes is 68 MM * 4 MM, and the length of the pipes is 26 M (including all local resistance losses). The value of λ is 0.03. What is the head required of the pump? Given that the pump efficiency is 60%, what is the power required of the pump? How do I calculate this? Could you explain it in detail? Dear experts
20 meters vertically should represent the minimum 20-meter drop for Yang Cheng; the pipeline loss is calculated at 1 meter per 10 meters. For Yang Cheng, 25 meters or more is sufficient. As for the pressure inside the tank, I think as long as the pump pressure is greater than the tank pressure, there’s no need to worry about it. In terms of efficiency, it’s unlikely that Yang Cheng’s system can achieve an efficiency of 60; I think 50 is more realistic. A motor with a power of 2.2 kilowatts and a grade of 4 should be sufficient. I’ll send you the diagram later to show you the calculation method.
2.2 kilowatts, grade 2; sorry, it was a typo
This software is good; I’d like to share it. What’s its name: lol
