In MKS system unit of viscosity is

Detailed Solution:

as we know viscosity = shear stress/ unit rate of strain = shear stress/ change in velocity/ change in distance = ((force/area) x change in distance)/ change in velocity = (force x distance)/ ((areax distance)/time)= (force, as we know in mks system force is denoted by kgf, distance with meter (m), area with m2, time with sec we get Viscosity in mks = kgf-m/(m3/sec) = kgf-sec/m2
