Absolute or dynamic viscosity is used to calculate Reynolds Number to determine if a fluid flow is laminar, transient or turbulent.

Reynold's Number - a definition

The absolute or dynamic viscosity of water depends on the temperature as indicated below:

Temperature		Absolute - Dynamic - Viscosity (cP)
(^oF)	(^oC)	Absolute - Dynamic - Viscosity (cP)
32	0	1.794
40	4.4	1.546
50	10.0	1.310
60	15.6	1.129
70	21.1	0.982
80	26.7	0.862
90	32.2	0.764
100	37.8	0.682
120	48.9	0.559
140	60.0	0.470
160	71.1	0.401
180	82.2	0.347
200	93.3	0.305

1 cP = 0.01 poise = 0.01 gram per cm second = 0.001 Pascal second = 1 milliPascal second = 0.001 N.s/m²
