Pressure at Pt is 200 kPa. All the valves are fully open gate valves, all the elbows are regular 90° threaded. For water, p:1000 kg/m3, 0.00108 N-s/m2. Other necessary data is given on the diagram. Assume the flow is incompressible and steady. Determine the volume flow...
A) Water moves in a pipe that has a diameter of 34 cm at 1 m/s, but then the pipe reduces to a diameter of 16 cm. Find the velocity of the water in the smaller portion of the pipe. B) Water in a hose with an area of 186 mm2 moves at 4 m/s, but then you cover part of the opening of the hose with your finger, and the water shoots out faster at 26 m/s . Find...
5.16. Water is flowing in a 3-cm-diameter pipe at an average velocity of Uav 2 m/s. Assuming water density of ρ-1000 kg/m 3 and viscosity μ-10-3 N s'm2, calculate the velocity at the center of the pipe, the shear τ at the wall, and the Reynolds number. Assuming laminar flow, calculate friction coefficient C and pressure drop dp/dx.
