Hydraulic System Design Tests

The SI unit of pressure is the:

When fully extended, a 50mm bore cylinder with a stroke of 600mm would contain approximately

If a pump requires 22kW of power to drive it when producing a flow of 60 L/min at a pressure of 175 bar, its overall efficiency is approximately:

The displacement of a hydraulic motor is usually measured in:

The equivalent of the CE mark in post Brexit UK is:

1 kgf is approximately equal to:

The overall efficiency of a pump is affected by:

In general, the pump type with the highest overall efficiency is:

The ISO standard which covers hydraulic graphical symbols is:

According to the Centre for Compact and Efficient Fluid Power, the average power transmission efficiency of a fluid power system is approximately:
