Sorry. You did not pass the The Grundfos Distributed Pumping Course test this time

Correct
01.
Q: How much flow is required to achieve almost 80 % of the capacity?
A: 50%
Correct
02.
Q: What is the benefit of aligning primary side flow with secondary side flow?
A: To avoid increasing pressure in the bypass pipe
Correct
03.
Q: Why is coil flow always correct in a distributed pumping system?
A: Because Magna 3 pump speed is modulated based on terminal unit load
Correct
04.
Q: What is the key design element in Grundfos Distributed Pumping?
A: The use of intelligent pumps instead of valves
Correct
05.
Q: Why must low-pressure non-return valves be installed for each cooling loop with AHU’s?
A: To avoid backflow in case the AHU unit is out of operation
Correct
06.
Q: Why is there in most cases no bypass flow with a distributed pumping system?
A: Because primary pumps try to match primary flow and secondary flow
