A Newtonian fluid of viscosity $\mu$ flows between two parallel plates due to the motion of the bottom plate (as shown below), which is moved with a velocity $V$. The top plate is stationary.
The steady, laminar velocity profile in the $x$ -direction is
- $V[\frac{y}{b}]$
- $V[(\frac{y}{b})^{2}-1]$
- $V[1 -(\frac{y}{b})^{2}$]
- $V[1 -\frac{y}{b}$]
