Dear all, If two identical pumps are connected in series, flow rate will remain unchange, but the pressure head will be doubled. If two identical pumps are connected in parallel , flow rate will be doubled, but the pressure head will remain unchanged. If three identical pumps are connected in series, flow rate will remain unchange, but pressure head will be tripled. If three identical pumps are connected in parallel , flow rate will be tripled, but pressure head will remain unchanged, And so on... It is a pump law, always ture. Hope this helps Fai
