can you help me with part b) please Question 3As a means of measuring the viscosity, a liquid is forced to flow through two very largedpYou can assume that the velocity betweendxparallel plates by applying a pressure gradient,the plates is given by1 dpu(y)2µ dx (h – y)where u is the fluid viscosity, dp/dx is the pressure gradient and h is the gap between theplates.a) Derive an expression for the shear stress acting on the top plate, Tw.b) Q' is the flow rate per unit width (i.e. has units of m?/s). Express Q' in terms of Tw.c) When the flow rate per unit width is Q' = 1.2 x 10-4 m²/s, the gap between theplates is 5 mm, the device estimates the shear stress at the top wall to be -0.05Pa. Estimate the viscosity of the fluid.d) When the tests are repeated for a blood sample, different estimates of viscosity are found fordifferent flow rates. What does this tell you about the viscosity of blood? Use appropriateterminology. (1 sentence).e) As the pressure gradient is increased, at a certain point the measurements cease to bereliable. Using your knowledge of fluid mechanics, give a possible reason for this. Useappropriate terminology. (1 sentence).

As a means of measuring the viscosity, a liquid is forced to flow through two very large dp You can assume that the velocity between dx parallel plates by applying a pressure gradient, the plates is given by 1 dp y(h-y) 2µ dx (h - y) u(y) = - where u is the fluid viscosity, dp/dx is the pressure gradient and h is the gap between the plates. a) Derive an expression for the shear stress acting on the top plate, Tw. b) Q' is the flow rate per unit width (i.e. has units of m?/s). Express Q' in terms of Tw.
