stormer

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 revolutions in response to an actuating weight. The viscometer is
 calibrated by measuring the time taken with varying weights while the
 mechanism is suspended 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
 <code>Time = (B1*Viscosity)/(Weight - B2) + E</code>
 where <code>B1</code> and <code>B2</code>
 are unknown parameters to be estimated, and <code>E</code> is error.
