6. Pressure Measurements from Flows. Water having a density of 998kg/m3 is flowing at the rate of 1.676m/s in a 3.068 -in.-diameter horizontal pipe at a pressure p1 of 68.9kPa abs. It then passes to a pipe having an inside diameter of 2.067 in. (a) Calculate the new pressure p2 in the 2.067-in. pipe. Assume no friction losses. (b) If the piping is vertical and the flow is upward, calculate the new pressure p2. The pressure tap for p2 is 0.457m above the tap for p1. 7. Frictional Pressure Drop in Flow of Olive Oil. Calculate the frictional pressure drop in pascal for olive oil at 293K flowing through a commercial pipe having an inside diameter of 0.0525m and a length of 76.2m. The velocity of the fluid is 1.22m/s. Use the friction factor method. Is the flow laminar or turbulent? Use physical data from Appendix A.4
