Webb20 juli 2024 · At a certain flow rate, this resistance suddenly increases and the fluid particles no longer follow straight lines but appear to move randomly although the average motion is still along the axis of the pipe. This type of flow is called turbulent flow. Osbourne Reynolds was the first to experimentally measure these two types of flow. WebbPipe roughness: you can provide the absolute roughness of the pipe here, e.g. for PE pipes usually a roughness of 0.003 mm is specified. After providing the desired parameters HTflux will calculate the surface resistance value of the pipes heat-transfer. By clicking on the “OK” button the value will be assigned for the boundary condition selected.
