What is the dynamic viscosity of water?

Table of Contents

The viscosity of water is 1.0016 millipascals⋅second at 20 °C. That is for its dynamic viscosity. Water viscosity varies depending on its temperature, and the higher the temperature is, the less viscous water is.

What is dynamic viscosity for air?

Viscosity of Air, Dynamic and Kinematic

Temp T, °C	Density Air ρ, kg/m3	Dynamic Viscosity Air µ, kg/m-s
15	1.225	1.802 x 10-5
20	1.204	1.825 x 10-5
25	1.184	1.849 x 10-5
30	1.164	1.872 x 10-5

What is viscosity of steam?

0.00020. Water vapor. (steam) 0.00013. Viscosity has the SI units Pascal seconds (Pa s) which is called the Poiseuille.

How do you find the dynamic viscosity of water?

The dynamic viscosity of water is 8.90 × 10−4 Pa·s or 8.90 × 10−3 dyn·s/cm2 or 0.890 cP at about 25 °C. Water has a viscosity of 0.0091 poise at 25 °C, or 1 centipoise at 20 °C. where A=2.414 × 10−5 Pa·s ; B = 247.8 K ; and C = 140 K….Water – Density Viscosity Specific Weight.

Temperature [°C]	Viscosity [mPa·s]
90	0.3150
100	0.2822

How do you calculate dynamic viscosity of water?

The dynamic viscosity of water is 8.90 × 10−4 Pa·s or 8.90 × 10−3 dyn·s/cm2 or 0.890 cP at about 25 °C. Water has a viscosity of 0.0091 poise at 25 °C, or 1 centipoise at 20 °C. As a function of temperature T (K): (Pa·s) = A × 10B/(T−C) where A=2.414 × 10−5 Pa·s ; B = 247.8 K ; and C = 140 K .

What is more viscous water or air?

Water, under normal temperatures, is about 50 times more viscous than air. Ice is 5 × 1016 times more viscous than air. One concludes that, in general, solids have extremely high viscosities whereas fluids have low viscosities. In the category of fluids, liquids generally possess higher viscosities than gases.

What is the density of water vapor?

Water vapor is also much less dense than the liquid or the solid. At 100°C and ordinary pressures, its density is 5.98 × 10–4 g cm–3, less than one thousandth that of solid or liquid mercury. A modern chemist would interpret these macroscopic properties in terms of a microscopic model involving molecules of water.
