(b) A Newtonian fluid flows in an annulus at a rate of 100 ml/s with a corresponding pressure drop of 500 Pa/m. If the radius, Ri, of the thin-walled inner pipe is 7.5mm and the area for flow in the annulus is 3 times higher than the area of the inner pipe, use the geometric parameter approach to determine the viscosity of the fluid, you are required to use the following equation (eq. 4.1) as part of your answer, 8V = =K * E (+4) a b+ n (equation 4.1) State all assumptions and any additional equations you use and clearly show all of your workings.
