alleryUnit of viscosity in SI:
AN s
BN/m
CPa s = kg/(m s) (poise = 10⁻¹ Pa s)
Dkg/m³
Answer & Solution
Correct answer: C. Pa s = kg/(m s) (poise = 10⁻¹ Pa s)
η: Pa s in SI. Or kg/(m s).
Dimensional formula ML⁻¹T⁻¹.
Water at 20°C: 1.0 × 10⁻³ Pa s.
**Historic:** poise (P) = 0.1 Pa s.
cP (centipoise) = water at room T.
