Question

During a walk around with the no. 3A pump on, what will the three system accumulators read?

a) 0 psi

b) 1500 psi

c) 3000 psi

d) both b and c

Answer 1

Without specifics on the accumulator system, it's difficult to answer conclusively, but typical accumulator readings with an operational pump would reflect the system's charged pressure, possibly 1500 or 3000 psi.

Step-by-step explanation:

The question asked about the readings of system accumulators during operation with pump no. 3A on. The accumulators in a hydraulic or pneumatic system are designed to maintain pressure, absorb shocks, and provide additional fluid flow when needed. For example, suppose the pressure gauge on a full scuba tank reads 3000 psi, which is approximately 207 atmospheres. When the valve is opened, air begins to escape because the pressure inside the tank is higher than the outside pressure, showing how accumulators work under gauge pressure vs. absolute pressure. Without specific details on the system the accumulators are a part of, it is difficult to provide a definitive answer about their readings. However, in a typical system where an accumulator is charged and functioning properly with an operational pump, we would expect the pressure readings to reflect the charged pressure of the system, which could be either 1500 or 3000 psi depending on the system's design requirements.
