How do you find the density of water at 20 degrees Celsius?

Water density at 20oC = 0.9982067 [g/cm3] or 998.21 [kg/m3]

## What is the viscosity of water at 22 degrees Celsius?

The kinematic viscosity of water (ν) at 22 degrees Celsius is 0.9565 Milimeter square per second (mm^2 / s).

Is water low or high viscosity?

low viscosity
Viscosity is often referred to as the thickness of a fluid. You can think of water (low viscosity) and honey (high viscosity).

### How do you find the speed of sound at 20 degrees Celsius?

Speed of sound c ≈ 331.3 + (0.6 × ϑ) in m/s. That gives e.g. at a temperature of ϑ = 20°C a speed of sound of: c ≈ 331.3 + (0.6 × ϑ) = 331.3 + (0.6 × 20) = 343.3 m/s.

What is water’s viscosity?

Viscosity of liquids is expressed in a variety of units: with the standard SI unit being the Pascal second or Poiseuille. That unit does not prove to be convenient for many uses, but note that the viscosity of water at 20°C is almost exactly 1 if expressed in centipoise or milli-Pascal seconds.

## What is the density of water at 20.5 degrees Celsius?

What is the density of freshwater at 20 C in Kg m3?

998.23 kg/m^3
At 20 degrees Celsius it is 998.23 kg/m^3 ( or 0.99823 g/cm^3).

### Is water viscosity constant?

That is for its dynamic viscosity. Water viscosity varies depending on its temperature, and the higher the temperature is, the less viscous water is. Water’s viscosity at, let’s say, 80 °C is 0.354 millipascals-second.

What is 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)

## What are the properties of water at different temperatures?
