Total head required12 m

Recommended head (15% margin) 13.8 m

Hydraulic power 49.05 W · Shaft power 81.75 W

How it works

  1. 1Head = 8 (vertical) + 20/10 + 4 x 0.5 = 12 m
  2. 2Recommended (with 15% margin) = 13.8 m
  3. 3Shaft power = 1000 x 9.81 x (1.5/3600) x 12 / 60% = 81.75 W

Reading the result

Head is NOT just the vertical height: friction along the horizontal run and each elbow adds up. Pick a pump whose rated head at YOUR flow point meets the recommended value — head drops as flow rises on the pump curve.

Rule of thumb (clean water, normal PVC/PPR pipe): 1 m head per 10 m horizontal run, 0.5 m per elbow/valve. Add 10-20% safety margin. If the end point needs residual pressure (e.g. shower needs 1-2 bar ≈ 10-20 m head), add it separately. Suction lift: a pump above the water surface can only lift about 8 m at most — prefer a submersible pump for deep wells.
