Sorry. You did not pass the 21 -Water Distribution test this time

Correct
01.
Q: How can a water tower be retained without affecting the required network pressure?
A: Using a small booster pump to supply water to the tank and a two-way hydraulically-operated control valve to remove water from the tank
Correct
02.
Q: What happens with the control valve if network pressure gets too low?
A: The control valve will open to maintain the minimum network pressure
Correct
03.
Q: What is unique about the algorithm used to manage pressure with DDD?
A: It is self-learning
Correct
04.
Q: What does DMAs make it easier to localise?
A: Leaks
Correct
05.
Q: What must zones be equipped with in order to achieve a fixed constant pressure setpoint at the discharge?
A: A booster pump or pressure-reducing valve
Correct
06.
Q: What is the general purpose of a water tower?
A: To keep the water in the distribution pipe network pressurised
Correct
07.
Q: What does DMA stand for?
A: District Metering Area
Correct
08.
Q: How is a DMA created?
A: By closing valves within the distribution pipe network to create a zone and installing flowmeters where valves are left open to register the volume of water supplied and removed from the DMA
