The stepped pipe would not be a problem if you know the flow and want to calculate the pressure drop, but the reverse calculation requires trial and error and this gets complicated when you have two different sizes in series, I have written up an example that explains this method of modeling the stepped pipe with one equivalent pipe of constant diameter at. Using the larger diameter would of course give the wrong velocity and would not make it clear if there is a risk of getting choked flow. Engineering ToolBox - Resources, Tools and Basic Information for Engineering and Design of Technical Applications! You can target the Engineering ToolBox by using AdWords Managed Placements. The pipe's flow rate is 0.654 cubic meters per second. pipe flow calculator diameter If there is a risk of choked flow occurring, then when using the modeling method I referred to above the smaller diameter pipe of the two should be used to model the line. flow partially pipe calculator calculation chart pipes equations fluid That's the key! A thicker fluid flows more slowly under the same pressure.
