The essence of lift

The essence of lift1. In the field of pump selection, the lift is often misunderstood as a direct indicator of how high or far water can be pumped. In reality, lift is the total energy that a pump can provide to overcome three major resistances: vertical height difference, pipeline friction resistance, and local resistance. In engineering, the calculation formula for lift is: H = Ho + ΔH + h. Here, Ho is the pressure required at the most unfavorable point, ΔH is the height difference of the liquid surface, and h is the total sum of all head losses. This formula explains a common phenomenon: even if the terrain is flat (ΔH=0), the pump still needs sufficient lift to counteract the pipeline resistance (h); otherwise, the water will not flow the expected distance. 2. The four major "invisible killers" of transport distance: the resistance effect of pipe materials and diameters. The impact of pipe diameter on resistance is geometrically amplified.
