Total questions: 10
Worksheet time: 5mins
Identify the type of energy loss that occurs due to fluid friction along the length of the pipe.
Explain what the term f represents in the Darcy–Weisbach equation.
Identify which type of loss occurs due to fittings, bends, and valves.
Calculate the head loss due to sudden enlargement where V1 = 3 m/s and V2 = 1.5 m/s
0.23
0.56
0.41 m
0.19 m
Interpret the term “Hydraulic gradient line (HGL)”
Line joining total energy heads
Line joining pressure heads + datum heads
Line joining velocity heads only
Line joining potential heads only
Compare energy losses in laminar and turbulent flow.
Recognize the typical range of Reynolds number for transition from laminar to turbulent flow in pipes.
Express why sudden enlargement causes energy loss.
Due to cavitation
Due to formation of eddies and turbulence
Due to air entrainment
Due to decrease in pressure head
Critically assess why minor losses cannot always be neglected in short pipes
Because they dominate when length is small
Because velocity changes are negligible
Because friction factor is small
Because they depend only on pipe material
Identify which factor increases the friction factor in turbulent flow.
