Peugeot 208 HYbrid Air 2L concept heading to Paris Motor Show

  • Peugeot has announced plans to bring the 208 HYbrid Air 2L concept to next month's Paris Motor Show.

    The original 208 HYbrid FE concept was unveiled last year at the Geneva Motor Show and now Peugeot is ready to present an evolution based on the same three-door 208 but featuring a wide array of changes. While the model upon which is based weighs 960 kg, this one has gone through a 100 kg diet as a result of a more extensive use of aluminum and carbon composites.

    The standard car is equipped with a three-cylinder 1.2-liter Puretech 82 gasoline engine and a five-speed manual gearbox but the concept uses a hybrid drivetrain featuring a mix of petrol and compressed air. It encompasses a compressed air tank below the trunk, a low-pressure tank near the rear axle (acting as an expansion chamber) and a hydraulic system with a motor and a pump in the engine bay.

    The aforementioned hydraulic system has a specially developed epicyclic transmission to provide the right balance between the two energy sources and also offers automatic shifting. Peugeot says the concept can be driven solely on compressed air when "Air" mode is selected while in "Petrol" mode it runs only on the gasoline engine. There's also a "Combined" mode in which the vehicle draws its power from the two energy sources.

    Crane Technical Practice 410: Use Of Fully Turbulent Friction Factor ...

  • Hello,


    Crane TP 410 provides methods to determine the K values for various standard fittings.  A turbulent friction factor (fT) is used for doing so and the figures are tabulated for various pipe diameters in the appendix A26.  The figures have been determined based on new steel.


    Can these figures be applied for materials other than steel piping please?


    The system I am looking at consists of polypropylene (PP) piping.  If I calculate fT for PP piping (using method described here: http://www.pumpfunda...com/help16.html


    Taking into account the absolute roughness for PP piping, the friction factor is reduced to approximately half vs steel piping.  The overall effect on the end calculation result (for my system) is a difference in flow capacity of ~5%, this would obviously be greater if the proportion to fittings vs straight pipe was greater.


    I have also checked my hand-calculation using AFT Fathom software and checked the help files within the software package to determine the methodology behind the calculations.  The software appears to apply the Crane values for fT for all piping material types.

    I need to calculate total dynamic head (TDH) for my swimming pool before sizing the pump, but the information on the Internet for friction loss and TDH seems to assume that there is only one pipe in the loop between the pool and the pump and return to

    You don't factor them in. There's only one suction line going into your pump and one return leaving it. All of your lines T in before it or after it. That's your bottleneck. Even if you have your valves set at 50/50 for either run, it doesn't matter.
