The circulation pump is located on the roof; the roof’s height is 20 meters, and the inlet of the circulation water tower is at a height of 7 meters. The circulating water flows downward around the workshop to the water tower. Without taking losses into account, should the head of the water pump be 7 meters or 27 meters?
I think, if pipe friction and elbow losses are not taken into account, it should be 7 meters, because 20 meters represents the potential energy, which is offset by the water flowing down and up the stairs
How many meters high is the inlet of the circulating water pump?
First, it is necessary to determine whether the system is a closed system In the case of a closed system, the head required by the circulation pump only needs to overcome system losses such as pipe friction. If it’s not a closed system, water cannot flow back to the circulation pump from the water tower
The circulating water returns to the tower; the tower is open, and the pump is located in the pool
Let’s take 1 meter as the unit; that means 21 meters above the ground
