After Building and Testing
the Pneumatic Circuit
Determine These Performance Characteristics
1. How many times will the pneumatic cylinder cycle at 50 psi
when the reservoir is charged to 150 psi?
2. What is the theoretical force of the piston at 50 psi?
3. What is the actual force of the piston at 50 psi?
4. What is the speed of the piston in inches per second at 50 psi?
5. Does pressure affect speed and if so, can you measure and
graph the relationship?
Which answers can be found mathematically?
Which should be measured directly?
