Calculate the performance of a simple pneumatic system using the following scenario.



The radius of the face of a pneumatic actuator is 50 mm. The radius of the actuator rod is 5 mm.



The actuator is fed from both sides by a switched pneumatic system with a flow rate of 0.5 litres/second.



Calculate the actuator speeds (forward and return) in metres per second (m/s). Keep your answers to four decimal places.
