A river water is flowing at `5ms^-1`. The depth of river water is 10m. What is the shearing stress between horizontal layers of the river water? Viscosity of water is 1 mili decapoise.

Text Solution

Verified by Experts

As per Newton.s law, `F=etaA(dv)/(dx)`
`therefore` stress=`F/A=eta(dv)/(dx)=10^-3xx3/10=0.5xx10^-3N//m^2`
