Question

The viscosity of water is 1 cp. Express the viscosity of water in:
(a) Pa. sec (b) stoke

Answer 1

Explanation:

Viscosity of water

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 . Viscosity of liquid water at different temperatures up to the normal boiling point is listed below.
