Oil, of specific gravity-0.87, and a viscosity 10 cp, flows through the vertical smooth pipe (figure below) at a rate of 4x10 m'/sec. A pressure drop AP is measured between the two points where the manometer intersects the pipe. SG= 0.87 4 m to 20 mm SG = 1.3 1. Determine if the flow is laminar, or turbulent. 2. Calculate the pressure drop AP, measured between the two points where the manometer intersects the pipe. 3. Determine the mass flow rate through the tube. 4. Determine the manometer reading h (oil level). 5. Now the oil flows at a rate of 4x10 m/sec, and there is no manometer connected to the pipe. The whole pipe length is now 4 m. Determine the pressure drop across the pipe.
