An incompressible, Newtonian fluid has a density of 0.80 x 103 kg/m3 at 25.0 C. Consider at the same temperature this fluid is flowing through a horizontal tube 0.50 m long and inner diameter 2.0 mm. For a pressure drop of 3.0 x 105 Pa, the volumetric rate of flow is measured to be 1.8 mL/s (milliliter per second). (a) [15 Points) Assuming steady, laminar flow and negligible entrance effect, from the flow data, find the viscosity of this fluid in centipoises (cp) and in Pa.s. (b) [5 Points] Experiments have shown that for Newtonian fluid flowing in circular tube driven by pressure, the laminar flow assumption is only realized for Reynolds number up to 2100; above that value, the flow will be turbulent and unsteady. For flow in circular tubes the Reynolds number is defined as DVp Re = 3 where D is the inner diameter of the pipe, V is the average flow velocity, p and u are the density and viscosity of the fluid. Based on this information, justify your calculation of the fluid viscosity in (a)
