This example demonstrates liquid flow driven by a pressure difference (pressure head) in a simple pipe system. You’ll calculate key hydraulic results—stagnation pressure loss, friction loss, flow rate, velocity, Reynolds number, and friction factor—for a 20 m long 4” Schedule 40 steel pipe carrying water at 25°C, with the inlet set to 1.1 barg and the outlet to 1.0 barg.
You’ll build the model in FluidFlow by adding boundaries and piping, defining the fluid and pipe data, selecting a results unit set, running the hydraulic analysis, and then validating the outputs by comparing FluidFlow results to a hand calculation.
