Table D-2
e full scale viscosity range for any DV1 model and spindle may be calculated using the equation:
Full Scale Viscosity Range [cP] = TK
*
SMC
*
10,000
RPM
where:
TK = DV1 Torque Constant from Table D-2
SMC = Spindle Multiplier Constant from Table D-1
e Shear Rate calculation is:
Shear Rate (
1
/
Sec
) = SRC
*
RPM
where:
SRC = Shear Rate Constant from Table D-1
