        The stormer viscometer measures the viscosity of a
        fluid by measuring the time taken for an inner cylinder
        in the mechanism to perform a fixed number of revolu-
        tions in response to an actuating weight.

   DDeettaaiillss::

        The viscometer is calibrated by measuring the time
        taken with varying weights while the mechanism is sus-
        pended in fluids of accurately known viscosity.  The
        data comes from such a calibration, and theoretical
        considerations suggest a nonlinear relationship between
        time, weight and viscosity, of the form

        Time = (B1*Viscosity)/(Weight - B2) + E

        where B1 and B2 are unknown parameters to be estimated,
        and E is error.
