![]() In addition, reading for viscosity was taken three. The viscosity of water decreases smoothly from the freezing point while the density remains essentially constant except for the small maximum in density near 4☌. nanofluid viscosity was determined by the rotational speed of spindle and measurement was in centipoise (cP). Because of its density of 1 g/cm3 (varies slightly with temperature), and its dynamic viscosity is near 1 mPas (see Viscosity of water section), the. In cgs units the unit is called the centistoke. The kinematic viscosity is the dynamic viscosity divided by the density of the fluid. This parameter is important for evaluating suitability of oil for frying applications. So the water increases inertia, but doesnt provide a resistance force. The smoke point is the temperature at which oil produces a continuous stream of smoke during heating. If the board is 1 kg, the water is 2 kg, and the force pushing the board is 6 N, then acceleration is not 6 N / 1 kg 6 m/s2, as is the case when there is no water, but 6 N / (1 kg + 2 kg) 2 m/s2, with a F/m. Refined canola oil has a higher viscosity than that of soybean oil. The metric prefix centi- is commonly used with poise because the viscosity of water at 20 degrees centigrade, under normal temperature and pressure, is near the equivalent of 1 poise. The unit centiPoise = 0.001 Pa s and is is sometimes written mPa s. Viscosity is the relative thickness or resistance of the oil to flow. These viscosities are at 20☌ except for the blood and blood plasma which are at body temperature, 37☌, and for steam which is at 100☌. The Poise is used in the table because of its more common usage. More commonly used is the dyne sec/cm 2 which is called Poise. Therefore, water has a viscosity of 0.0091 poise Viscosity and density are two different terms where viscosity is the thickness of fluid and density refers to the space between its particles. Viscosity has the SI units Pascal seconds (Pa s) which is called the Poiseuille. In CGS unit, the value of viscosity is 8.90 × 10- 3 dyn·s/cm2 or 0.890 cP.
