Consider a fluid flow between two parallel fixed plates 5 cm apart. The velocity distribution for the flow is given by u(y) = 120 (0.05y y²) m/s where y is in meters. The fluid is water at 10°C. Calculate the magnitude of the shear stress (T) acting at the lower plate when y = 0. Use μ = 1.308 x 10-³N s/m², where t = du μ² dy -
