Viscosity of water depending on the temperature

Viscosities of fluids vary depending on the temperature and pressure. For liquids, the  viscosity at atmospheric pressure is expressed as a function of the temperature.
Based on Poiseuille\\\'s experiments, Helmholtz proposed the following empirical formula to estimate the viscosity of water.

¥ì = ¥ì0 / (1+0.03368t+0.000221t©÷) 

¥ì  : water viscosity at t¡É (kg/m¡¤s) 
¥ì0 : water viscosity at 0¡É (0.00179kg/m¡¤s) 
t  : temperature (¡É)
