Appendix A
EXAMPLE: CAP 1000+L Viscometer; Cone (02); running at 750 RPM;
temperature25.0°C;%FSR=73.8.Determinetheviscosity(poise),
shear stress (dynes/cm2), shear rate (sec-1).
Using Equation A2, determine the full scale viscosity range at 750 RPM:
FullScaleViscosityRange(poise)=
3,750
=5.00poise
750
Using Equation A5, determine the viscosity at 73.8% of full scale range:
Viscosity(poise)=5.00 (poise) x
73.8
=3.69poise
100
Using Equation A4, determine the shear rate:
Shear Rate (sec
-1
)=
(2)(3.1416)(750)
=10,000sec
-1
(60)(sine 0.45)
Using Equation A2, determine the shear stress:
 ShearStress(dynes/cm2)=(3.69)(10,000)=36,900dynes/cm2
