Two large vertical parallel plates separated by a gap of a \[d=1\text{ }mm\]have a highly viscous liquid of density\[800kg/{{m}^{3}}\]and viscosity coefficient \[\eta =5\]poise flowering steadily under gravity in between the gap. Find the velocity gradient of flow near plates surface in\[{{\sec }^{-1}}\].\[(1\text{ }poise=0.1Ns/{{m}^{2}})\]
