An oil is being pumped inside a 10.00 diameter pipe at a Reynolds number of 2100. The oil density is 855 kg/m^3 and the viscosity is 2.1 x 102 Pa-s. a) What is the velocity in the pipe? b) It is desired to maintain the same Reynolds number of 2100 and the same velocity as in part (a) using a second fluid with a density of 925 kg/m' and a viscosity of 1.5 x 10 Pa-s. What pipe diamater should be used?
