The figures and tables below shows how water viscosity changes with temperature (°C and °F) at water saturation pressure (which for practicle use, gives the same result as atmospheric pressure at temperatures < 100 °C (212°F)). One figure showing relative viscosity with variations in pressure and temperature is also included.
