1000 lb/in2 is in an accumulator. If 3000 lb/in2 of hydraulic fluid is pumped in, what is the pressure on the air side?
- 3000 lb/in2.
- 4000 lb/in2.
- 1000 lb/in2.
Explanation
The gas and the fluid are separated by a free piston or diaphragm that transmits pressure, so the air side pressure always equals the fluid side pressure once balanced. Pumping fluid in at 3000 lb/in2 compresses the gas until it too reads 3000 lb/in2. The 1000 lb/in2 was only the pre-charge before fluid entered.

THE ANSWER IS WRIGHT AS THE 3000IB/IN2 IS THE ACTUAL HYDRAULIC PRESSURE AND 1000IB/IN2 IS THE ACCUMULATOR PRESSURE. ACCUMULATOR PRESSURE IS NEVTR ADDED TO THE ACTUAL PRESSURE AS THE ACCUMULATOR IS THERE ONLY TO STORE HYDRAULIC UNDER PRESSURE AND REDUCE FLUCTUATIONS WHEN ACTUAL HYDRAULIC PRESSURE IS BELOW 1000IB/IN2

alberto is right guys it isnt 4000 you should read the notes.
