Plastic Viscosity (PV), cP = 600 RPM reading - 300 RPM reading
Yield Point (YP), lb./100 ft 2 = 300 RPM reading - Plastic Viscosity (PV)
Apparent Viscosity (AV), cP = 600 RPM reading / 2
Gel Strength, 10 second, lb./100 ft 2
= the maximum dial deflection after 10 sec.
Gel Strength, 10 minute, lb./100 ft 2
= the maximum dial deflection after 10 min.
