What is cP in viscometer?
Sophia Dalton What is cP in viscometer?
The poise (symbol P; /pɔɪz, pwɑːz/) is the unit of dynamic viscosity (absolute viscosity) in the centimetre–gram–second system of units. A centipoise is one hundredth of a poise, or one millipascal-second (mPa⋅s) in SI units (1 cP = 10−3 Pa⋅s = 1 mPa⋅s). The CGS symbol for the centipoise is cP.
What is KU unit viscosity?
The viscosity is reported in Krebs units (KU), which are unique to Stormer viscometers. Vibrating viscometers can also be used to measure viscosity. Resonant, or vibrational viscometers work by creating shear waves within the liquid.
How do you find the viscosity of a centipoise?
Equation (1) is known as the Newtons Law of Friction. Water at 20.2oC (68.4oF) has the absolute viscosity of one – 1 – centiPoise….Dynamic (absolute) Viscosity.

How do you convert poise to centipoise?
1 Poise [P] = 100 Centipoise [cP] – Measurement calculator that can be used to convert Poise to Centipoise, among others.
What is Brookfield viscosity?
Brookfield viscosity usually refers to a viscosity measurement performed with a Brookfield Viscometer, sometimes refered to as a Brookfield viscosimeter.
What is a viscometer and how does it work?
There are several models of viscometer available from Brookfield but the majority operate in the same manner: the viscometer motor rotates the spindle at a defined speed (measured in rpm) or shear rate and the viscometer measures the resistance to rotation and reports a viscosity value.
What does a typical viscosity spec look like?
So a typical spec may look like: Brookfield LVDVII+, 500ml of sample in 600ml beaker, spindle 3 at 20rpm, 25°C, take measurement after 30s. Here are some typical reported test methods and viscosity specs for a range of products: Viscosity of anti-icing fluid, ASTMD2196 Method B: Brookfield LVT Viscometer with Small Sample Adapter SC4-31/13R, 0.3rpm
What is the viscosity range for spindle readings at 60 rpm?
Spindle # Multiplier for Readings at 60 rpm Viscosity Range 1 1 1 to 100 cP 2 5 50 to 500 cP 3 20 400 to 2,00 cP 4 100 1,000 to 10,000 cP. Long-term retardants have typically been measured using a #2 spindle for viscosities up to 500 cP and a #4 spindle for viscosities greater than 500 cP.
