By tracking the pressure gradient in real-time, the feature automatically flags areas where the pressure drops below the fluid’s vapor pressure. This visual warning prevents cavitation risks before hardware is purchased, ensuring that pumps are placed at the correct elevation and that pipe diameters are sufficient to maintain positive pressure.
The software finds the operating point where the system curve intersects the pump curve, an essential feature for avoiding cavitation or motor overload. pipe flow expert
The tool generates a precise System Resistance Curve , plotting Head vs. Flow for the network. Users can overlay specific Pump Curves directly onto this graph. The intersection point (Operating Point) is calculated instantly, showing exactly how a specific pump will perform within that specific system configuration. By tracking the pressure gradient in real-time, the
Where ( h_f ) = head loss (ft or m), ( f ) = friction factor, ( L ) = pipe length, ( D ) = diameter, ( V ) = velocity, ( g ) = gravity. The tool generates a precise System Resistance Curve
| Tool | Primary Strength | Weakness vs. Pipe Flow Expert | | :--- | :--- | :--- | | | More advanced compressible and heat transfer options | Higher cost, steeper learning curve | | EPANET | Free, EPA water distribution standard | No GUI pump curve fitting, weaker fitting database | | FluidFlow (Flite) | Excellent two-phase and slurry | More expensive, less common in fire protection | | Manual Excel solver | Zero cost | Impractical for >10 pipes, no convergence guarantee |
: The software comes pre-loaded with extensive databases for fluid properties, pipe materials, and fittings/valves.
The software includes a from Crane TP-410, ASHRAE, and manufacturer data. Users can also import custom pump curves from CSV files.
