Whole milk at 293 K having a density of 1030 kg/m and a viscocity of 2.12 cp is flowing at a rate of 0.605 kg/s in a glass having a diameter of 63.5 mm. Calculate the Reynold's number. 10. An oil being pumped inside a 10 mm diameter pipe at a Reynold's number of 2100. The oil density is 855 kg/m and viscosity of 2.1 x 10 Pa-s. What is the velocity in the pipe? It is desired to maintain the same NRe and same velocity using a second fluid with a density of 925 kg/m and a viscosity of 1.5 x 102 Pa-s. What pipe diameter should be used? 11. Water having a density of 998 kg/m is flowing at the rate of 1.676 m/s in a 3.068 in diameter horizontal pipe at a pressure of 68.9 kPa abs. What is the new pressure if it passes to a 2.067 in diameter pipe?
