Question
Question 1 25%
Light crude oil is imported and stored on site in a 10m high bunded tank with a floating roof.
The crude oil pump is located in the bunded area. The crude oil is pumped via a pipe at the
continuous volumetric flow rate of 1million tonnes per annum to a fractionating column some
50m from the tank. The feed to the column is 20m above ground level. The oil goes through
6 right angle bends and a control valve with 2 block valves in a manifold with a second pump
ready to be brought online in the event of a failure.
Determine the size of pipe you will need to minimise cost. Design a pump suitable for this
task. Consider where this volume sits on a pump curve and determine if more than one
pump is required. You can assume the tank is at 25 degrees C and that its density is
0.8tonne/m3. What, if any, operational aspects will occur as the tank is emptied?

- Example 7.7. The pipe bend in Fig. 7.9 is attached to the rest of the piping system by two flexible hoses, which transmit no forces. Water enters in the + x direction and leaves in the -y direction. The flow rate is 500 kg/s, and the cross-sectional area of the pipe is constant = 0.1 m² The pressure throughout the pipe is 200 kPa gauge. Calculate Fx and Fy, the x and y components of the force in the pipe support. Flow -X System boundaryarrow_forward6. Air at 205 kPa and 37 °C flows upward through a 6-cm diameter inclined duct at a rate of 65 L/s. The duct diameter is then reduced to 4-cm through a reducer. The pressure change across the reducer is measured by a water manometer. The elevation difference between the two points on the pipe where the two arms of the manometer are attached is 0.20 m. Determine the differential height between the fluid levels of the two arms of the manometer.
