    Bicycle Fluid Trainer Question

    Well, from your link I see a look up table for Z, but it is dependent on pressure which is what I am trying to solve for. Also, there is no mansion of humid air, which I think would play a large role. It does say that the ideal gas law is probably a good approximation below 2 atm, I think I...

    Bicycle Fluid Trainer Question

    I need some help solving for pressure. Say the initial conditions are: Temperate= 291 K Pressure= .1 mPa (atmosphere) Air Volume= 45 ml Final conditions: System heated to 374 K Oil expands and compresses air volume to 35 ml What is the pressure? Thanks

    Bicycle Fluid Trainer Question

    A bicycle fluid trainer works with the bicycle tire turning a rotor in a sealed chamber of oil. I'm trying to calculate pressure rating of the seals based on the following inputs. There is some air in the chamber to allow for oil expansion and I know the cold temperature and oil volume, so I...

    Heat Straitening Incoloy 800 Rods, Help!

    We will probably not look into the "chemical blackening" because it would be too high risk for our main process. Its a good suggestion. Does anyone have any experience with fixtures and materials that go inside the heat treatment chamber?

    Heat Straitening Incoloy 800 Rods, Help!

    Compositepro, I don't think chemical blackening would work in a vacuum, because of out-gas contamination from the coating.

    Heat Straitening Incoloy 800 Rods, Help!

    My work uses Watlow Multi Cell heater rods in in its vacuum process, but they don’t come the way we want them. We have a supplier do the following: Straitening (they can come bowed ¼ in), Oxidation (increases the radiation heat transfer and looks black), along with other things. The problem is...
