4. Oil (p=870 kg/m³ and u=0.036ON.s/m²) is flowing through the100-mm-diameter pipe shown in the figure. The pressure at location A is 34.25kPa. Determine the volumetric flow rate at location B and the center line velocity. What would be the flow rate if the pipe is pointing downwards? Make sure to validate your assumptions. (Hint: Watch video “Chapter-8 Inclination.mp4")
