How to Perform Basic Hydraulic Calculations
The following formulas represent the core calculations performed by FHC software:
-
Flow Velocity (v):
v = Q/A where:
- Q = volumetric flow rate (m³/s)
- A = cross-sectional area of pipe (m²)
Recommended velocity ranges:
- Suction lines: 0.6-1.2 m/s
- Pressure lines: 2.5-5.0 m/s
- Return lines: 1.5-3.0 m/s
-
Pressure Drop (ΔP):
ΔP = f × (L/D) × (ρv²/2) where:
- f = Darcy friction factor
- L = pipe length (m)
- D = pipe diameter (m)
- ρ = fluid density (kg/m³)
- v = flow velocity (m/s)
-
Reynolds Number (Re):
Re = (ρvD)/μ where:
- ρ = fluid density (kg/m³)
- v = flow velocity (m/s)
- D = pipe diameter (m)
- μ = dynamic viscosity (Pa·s)
Flow regimes:
- Laminar: Re < 2300
- Transitional: 2300 < Re < 4000
- Turbulent: Re > 4000

Common Mistakes to Avoid in Hydraulic Calculations
- Ignoring Fluid Properties: Viscosity changes with temperature can dramatically affect pressure drop. Always use temperature-corrected values.
- Overlooking Minor Losses: Valves and fittings can account for 30-50% of total system pressure drop in complex systems.
- Incorrect Pipe Roughness: Using generic roughness values instead of material-specific data can lead to 15-25% errors in pressure drop calculations.
- Neglecting System Transients: Water hammer effects can create pressures 5-10 times the steady-state values, leading to pipe failures.
- Improper Unit Conversion: Mixing metric and imperial units is a common source of calculation errors.
- Underestimating Safety Factors: Always design for peak demand conditions, not average operating points.
