Which statement about the system is supported by the given information?

• A. The cylinder moves faster due to the extra oil from the accumulator when used with the pump.
• B. The cylinder's speed is unaffected by the accumulator.
• C. The accumulator causes the oil to heat up.
• D. The pump alone provides more speed than with accumulator.

Answer: (B)

The speed of the cylinder is governed by the flow rate supplied to it by the pump; the accumulator’s role is to store pressurized oil and provide extra flow only during transient demands or to smooth pressure, not to continuously increase the cylinder’s velocity. So, with a fixed pump flow, the cylinder’s average speed remains the same whether the accumulator is in the circuit or not. The accumulator helps handle surges and maintain pressure, but it does not inherently make the cylinder move faster in steady-state operation.
