This example shows how to model liquid flow driven by a centrifugal pump in FluidFlow, transferring water at 25°C from an open storage tank (0 barg) to an open overhead tank (0 barg) while overcoming elevation rise and piping losses. The system includes 15 m equivalent length of 6” SCH 40 steel pipe on the suction side and 15 m equivalent length of 4” SCH 40 steel pipe on the discharge side, with elevations defined for the tank bottom (2 m), pump centerline (1 m), and discharge endpoint (10 m).
Using a target flow rate of 100 m³/hr, you’ll build the network, define boundaries, fluid, piping and pump data, select a results unit set, and run the hydraulic analysis. You’ll then review and verify key outputs including pipe velocities, Reynolds numbers, Darcy friction factors, friction losses, required pump head and differential pressure, and NPSH available—comparing FluidFlow results to a hand calculation for validation.
