Common data

g = 9.81 m/s².
The standard properties of water are density: ϱH2O=1kg/dm3ϱH2O=1kg/dm3 exactly, kinematic viscosity: νH2O=1.02⋅10−6m2/sνH2O=1.02⋅10−6m2/s.

Lubrication oil is pumped at a rate of 30.5 cm³/s through a 13 m long D = 7.5 mm diameter pipe on a steam engine. The pipe roughness is ε = 1.5 µm. The density of the lubricating oil is 960 kg/m³, its dynamic viscosity at 25 °C is 4 Pa·s.

Do not forget to tick the appropriate units!

• What is the weight flow rate of the lubricating oil?
• What is the momentum flow rate in the pipe?
• What is the Reynolds number?
• What is the head loss along the pipe?
• What is the pressure drop along the pipe?
• Calculate the power the oil pump needs to deliver.

• As the temperature rises to 95 °C, the dynamic viscosity drops by a factor of 100. How does this change the flow type and the required power?

• The new Reynolds number will be:
• The power of the pump becomes:

(a) In terms of relative strength, put fcd (design strength of concrete), fck
(characteristic strength of concrete) and fcm (mean strength of
concrete) in order from lowest to highest strength. (3)
(b) Approximately, what is the tensile strength of concrete as a
percentage of its compressive strength? (1)
(c) Draw and name all necessary reinforcement for the simply supported
beam and static loading case shown at Figure 3a. (6)
(d) Recreate the table in Figure 3b in your script books and fill in by
writing “Poor” and “Good” words to describe the property of the
material.

What document summarizes the financial position of the construction company?

Question options:

An oil company wishes to construct a pressurised pipeline of 300 mm diameter to convey freshwater, of bulk modulus 2.10x109 N/m2 from a desalination plant to a refinery at a rate of 350 l/s and with a pipe period of 4 seconds. Calculate the corresponding theoretical surge pressure induced within the pipeline by the complete closure of an on-line valve (located at the end of the pipe) in 8 seconds. The valve generates non-uniform retardation of type R = At0.65. The steel pipe has 5 mm thick walls, a Young’s modulus of 2.1x1011 N/m2 and Poisson’s ratio of 0.28. Calculate the pressure transients at the valve in the pipeline, for the first 12 seconds after the valve starts to close. Assume that pipe is longitudinally restrained.
