Project Details

Inputs

Flow (L/s)

Straight Pipe Length (m)

Specific Gravity (SG)Defaults to 1.0 for water.

Internal Diameter (mm)

Pipe Diameter Selection

Metric PN / DN Rural Pipe Custom Manual

Pressure Class (PN)

Nominal Size (DN)

Diameter Source

Select a pipe option to populate the internal diameter.

Static and Pressure Requirements

Elevation Head Method

Manual Elevation Head Calculate from RLs

Elevation Head (m)

Required Discharge Pressure (kPa)

Discharge Pressure Head (m)

Head Notes

Manual elevation head is currently active.

Fittings (Equivalent Length)

Counts below are converted to equivalent length using factor x D.

Results

Equivalent Length of Fittings

0.00 m

Estimated Friction Loss

0.00 m

Flow Velocity

0.00 m/s

Elevation Head

0.00 m

Discharge Pressure Head

0.00 m

0 kPa

Total Required Head

0.00 m

Velocity Note

Within typical guideline (≤ 1.5 m/s).

Formula

Friction loss: hf = 0.001 × (Q/1000)^1.85 × (D/1000)^-4.87 × (L + Leq)
Velocity: v = (Q / (πD²/4)) × 1000
Pressure head: Hp = P(kPa) / (9.81 × SG)
Total required head: Ht = Elevation + Pressure Head + hf
