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:
