Question

The relative velocity of two infinitely wide parallel plates

Answer 1

Answer:$0.01 N/m^2$

Explanation:

Given

Distance between Plates(dy)=1 cm

Relative Velocity(du)=10 cm/s

Dynamic viscosity$\left ( \mu \right )=0.001 Ns/m^2$

We know shear stress is given by $\tau$

$\tau =\frac{\mu du}{dy}$

where du=relative Velocity

dy=Distance between Plates

$\tau =\frac{0.001\times 10}{1}=0.01 N/m^2$
