In a turbine cycle, an example is given for which pump arrangement?

• A. Parallel Pumps
• B. Series Pumps
• C. Pump Deadhead
• D. Pump Runout

Answer: (A)

When you want more flow without raising the pressure head, you connect pumps in parallel. In parallel, the pumps share the load and the total flow increases for the same discharge pressure, which fits a turbine cycle where the feedwater demand can vary and you want to maintain adequate flow without boosting boiler pressure. If pumps were in series, you’d raise the discharge pressure (head) but not gain much extra flow, which isn’t the scenario described. The other terms describe operating states rather than a configuration to meet higher flow demands, so they don’t match the example being given.
