 [A]. N-m/s2 [B]. N-s/m2 [C]. poise [D]. stoke

Explanation:

No answer description available for this question.

 Naveen said: (Aug 27, 2014) The unit of dynamic viscosity is kg/m.s,or equivalently, N.s/m2. A common viscosity unit is poise, which is equivalent to 0.1 Pa.s (or centipoise,which is one-hundredth of a poise).

 Siddu said: (Jul 15, 2016) Answer should be (D) Stoke or m2/sec.

 Vicky said: (Oct 16, 2016) 1 pa s = 1Ns/m^2 = 1kg/ms.

 Khuidad said: (May 15, 2017) Stoke is the unit of kinematic viscosity.

 Vishnudath said: (Dec 3, 2017) DYNAMIC VISCOSITY:Nsm^-2. Kinematic viscosity:stoke.

 Basavaraj Kumbar said: (Jul 23, 2018) The unit of dynamic viscosity in the SI system is N-s/m2. The unit of dynamic viscosity in the CGS system is POISE. The unit of kinematic viscosity in SI system is m2/s. The unit of kinematic viscosity in CGS system is STOKE.

 Sachin Sethi said: (Apr 24, 2019) The unit of dynamic viscosity in the SI system is N-s/m2.

 Imran Khan said: (Jun 25, 2019) The unit of dynamic viscosity is stoke or m2/sec.

 Santosh said: (Jul 16, 2019) Pascal-second is the another unit of dynamic viscosity.
