The flow rate is twice the flow rate when each pump operates independently. B. The flow rate is less than twice the flow rate when each pump operates independently. C. The head at the operating point when the pumps operate independently is lower than the head at the operating point in parallel. D. The head at the operating point when the pumps operate independently is higher than the head at the operating point in parallel. E. The flow rate at the operating point when the pumps operate independently is greater than the flow rate at the operating point in parallel. Answer: BC
