This example demonstrates gas flow driven by a pressure difference (pressure head) using a simple piping system in FluidFlow. You’ll analyze air at 25°C flowing through a 20 m long 4” Schedule 40 steel pipe, with the inlet set to 1.1 barg and the outlet to 1.0 barg.
You’ll build the model by adding boundaries and piping, defining the gas and pipe data, selecting a results unit set, and running the hydraulic analysis. The key results reviewed include stagnation pressure loss, friction loss, flow rate, velocity, Reynolds number, and friction factor—then you’ll validate the FluidFlow outputs by comparing them to a hand calculation.
