SUMMARY
The discussion centers on calculating the position of a plate between two fluids, with a final answer of 4.59 mm. The key equations used include the shear stress equation, τ = μ(du/dy), and the relationship between the shear stresses of the two fluids, expressed as μ1(du/dy1) = μ2(du/dy2). The user derives the position of the plate by substituting variables into the equation, ultimately finding y1 = 3.31 mm. However, there is contention regarding the assumption that the shear stress exerted by both fluids on the plate is equal, suggesting the problem may be under-specified.
