This example shows how to model gravity-driven liquid flow in FluidFlow using a simple 20 m long 4” Schedule 40 steel pipe carrying water at 25°C. With the inlet and outlet pressures both set to 1.0 barg and an elevation drop from 5 m to 3 m, the model demonstrates how static head (potential energy) drives flow from a higher source to a lower sink.
You’ll build the network, define the boundaries, fluid, and pipe data, choose a results unit set, run the hydraulic calculation, and review key outputs such as stagnation pressure loss, friction loss, flow rate, velocity, Reynolds number, and friction factor—then compare the FluidFlow results to a hand calculation for verification.
