1 If already known the slurry production process minimum, normal, maximum flow, maximum flow should be selected.
2 When only given normal flow capacity, you should consider leaving a certain margin.
ns>100 which unexpectedly large flow of low-lift pump, take 5% flow margin
ns < 50 lifted a small flow pump, take 10% flow margin
50 ≤ ns ≤ 100, take 5% flow margin, if with poor working and operating conditions, flow margin should be taken as 10%.
3 Weight flow should be converted into a volume flow.
Better flow calculation of slurry pump can improve work efficiency.
