1. Whole milk having a density of 1030kg/m3 and viscosity of 2.12cp is flowing at a rate of 0.605kg/s in a glass pipe having a diameter of 63.5mm. a. Calculate the Reynolds number. Is the flow turbulent? b. Calculate the flow rate needed in m3/s for a Reynolds number of 2100 and velocity in m/s. 2. Oil is being pumped inside a 10mm diameter pipe at a Reynolds number of 2100 . The oil density is 855kg/m3 and the viscosity is 2.1102Pa.s a. What is the velocity in the pipe? b. It is desired to maintain the same Re of 2100 and the same velocity as in part (a) using a second fluid with density 925kg/m3 and a viscosity of 1.5102 Pa.s. What pipe diameter should be used
