Question

The relative velocity of two infinitely wide parallel plates

thatare 1cm apart is 10cm/s. If the dynamic viscosity of theliquid
between the plates is 0.001 N s/m2 what is theshear
stress between the plates?

Answer 1

Answer:
`0.01 N/m^2`

Step-by-step 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 =(\mu du)/(dy)`

where du=relative Velocity

dy=Distance between Plates

`\tau =(0.001* 10)/(1)=0.01 N/m^2`
