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
