If the shearing stress having stress b/w the horizontal layers of water in a river is 1.5 milli newton/

{m^2}

and 

{\eta _{\mathrm{water}}} = 1 \times {10^{ - 3}}pa,s

then the velocity gradient is 

{s^{ - 1}}

View answer and explanation

Correct option: A

1.5

Option A (1.5) is correct because the velocity gradient is calculated by dividing the shearing stress by the viscosity.
