Problems with vacuum pumps

May I ask, for a vacuum pump and vacuum tank system operating at around -60 KPA, to what height can water be pumped? ? The pump and the water intake equipment are at roughly the same height; in between them there is a 10M long vacuum tube with a DN50 diameter, while the rest are horizontal pipelines with a DN250 diameter, located 3M above the pump. The inlet is a DN80 diameter hose. Under these vacuum conditions, is it possible for water to be pumped through a pipeline 10M high? I don’t quite understand; I hope the teachers can give me some guidance.

LZ didn’t explain it in enough detail; it’s not clear what they meant. However, it can be calculated using the hydrostatic equation p=p0+pgh

Simply put, can water be pumped to a height of 10 meters in a vacuum tank at a negative pressure of 60 kPa?

Don’t understand; wait for an expert to explain: curse:
