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