Water Pumps

How to calculate required pressure

Centrifugal Type

1. Required volume of water = 110 liters/min

2. Suction Head = 5m.........................................(a)

3. Discharge Head = 18m...................................(b)

4. Friction Loss (as of 10%)

  a) Pipe Length (Suction) = (4m + 11m) x 0.1c = 1.5m.......................................(c)

  b) Pipe Length (Discharge) = (15m + 40m) x 0.1 = 5.5m...................................(d)

5. Total Dynamic Head = 5m (a) + 18m (b) + 1.5m (c) + 5.5m (d) = 30m
