Correct
Q: Which of the following is one correct method to avoid cavitation?
A: Reduce the friction loss in the suction pipe.
Correct
Q: How can friction loss in a system be minimised?
A: By increasing the pipe diameter
Correct
Q: How is the relationship between these three factors described in an equation?
A: P = Q x H x c
Correct
Q: What are the effects of cavitation on pumps?
A: Pitting of impeller and pump housing
Correct
Q: Friction loss is dependent on the [xxxxxxxx] of the fluid.
A: Velocity
Correct
Q: Select the three parameters of most interest in water pumping systems:
A: Flow, head and energy
Correct
Q: What causes cavitation?
A: Cavitation occurs when water changes its state from vapour to water at low pressure.
Correct
Q: Identify the false statement.
A: Cavitation can occur when water is flowing in a pipe and a valve is closed too quickly.
