Two flat plates are oriented parallel above a fixed lower plate as shown The top plate, located a distance $b$ above the fixed plate, is pulled along with speed $V.$ The other thin plate is located a distance $cb,$ where $V_1\frac{V_1}{V}c=>V$

$=>V_1\frac{V_1}{V}0.$

This plate moves with speed $V_1,$ which $is$ determined $by$ the viscous shear forces imposed $onitby$ the fluids $on$ its top and bottom. The fluid $on$ the top $is$ twice $as$ viscous $as$ that $on$ the bottom. Plot the ratio$\frac{V_1}{V}as$ a function $ofc$ for $0.$
