Correct
Q: Which of the following parameters is not used for calculating pump efficiency?
A: Time
Correct
Q: Identify the false statement.
A: Cavitation can occur when water is flowing in a pipe and a valve is closed too quickly.
Correct
Q: Select the three parameters of most interest in water pumping systems:
A: Flow, head and energy
Correct
Q: What are the effects of cavitation on pumps?
A: Pitting of impeller and pump housing
Correct
Q: How is the relationship between these three factors described in an equation?
A: P = Q x H x c
Correct
Q: Identify the correct formula for calculating pump efficiency.
A: (p x H × Q)/(367 × P1)
Correct
Q: What causes cavitation?
A: Cavitation occurs when water changes its state from vapour to water at low pressure.
Correct
Q: Identify the true statement.
A: If all the parameters are recorded immediately after the pump has been installed, you can use them as benchmark against future data.
