    Formula for pressure in process window

    We are working on process validation and this web site has been a big help. My question, Is there a formula for calculating the center point for Pressure in the process window?

    Hi Dean,
    There is a formula and I will dig it up for you soon. It is basically the center of gravity of the quadrilateral. For now, if you have a parallelogram, simply take the average of the pressures and the average of the temperatures.
    Will post soon.
