Water in a river 20 ~m deep is flowing at a speed of 10 ~ms ⁻¹ . The shearing stress between the horizontal layers of water in the river in Nm ⁻² is (Coefficient of viscosity of water =10⁻³ SI units)
Options
- A1 10⁻²
- B0.5 10⁻²
- C1 10⁻³
- D0.5 10⁻³
Correct answer
D. 0.5 10⁻³
Step-by-step solution
aligned Shearing stress & = ( d v d x ) & =10⁻³ ( 10 20 ) & =0.5 10⁻³ Nm ⁻² aligned
