May I ask about the head and power required for the pump?
Thread Content
The pump has a flow rate of 80 cubic meters per hour, an operating temperature of 52 degrees, and it is used in a tower 30 meters high. What power and head should be selected? I’m not very familiar with choosing pump models; I would appreciate your advice
It can be calculated as follows: Head = Pump inlet pressure + Outlet pipeline losses + 30 meters. You can add a little extra margin on top of this value. To calculate power, you need to provide the density of the fluid at operating temperature. Shaft power = density × 9.81 × flow rate × head. Motor power = shaft power ÷ pump efficiency × 1.15. Using these formulas, it’s possible to determine the head and power required for the pump. Another key factor is the net positive suction head; be sure not to forget this, otherwise you might encounter problems if the pump doesn’t meet the expected performance levels after purchase. These days, it’s usually sufficient to provide the conditions to the pump manufacturer, who will choose the appropriate one for you – there’s no need to do the calculations yourself! !
How was this calculated? I don’t understand it; it’s too complex
Hehe, thanks for the explanation from above; it was of great help to me.
