The full scale viscosity range for any DV-II+Pro model and spindle may be calculated using the
equation:
Full Scale Viscosity Range [cP] = TK * SMC * 10,000
RPM
where:
TK = DV-II+Pro Torque Constant from Table D-2
SMC = Spindle Multiplier Constant from Table D-1
The Shear Rate calculation is:
(Shear Stress (D/cm
2
)) = Viscosity (P) * Shear Rate (1/sec)
= TK * SMC * SRC * TORQ
