for first year engineering introduction to mechatronics

1. A pump supplies oil at 0.0016 m3/s to a 40-mm-diameter double-acting hydraulic cylinder. If the load is 5000 N (extending and retracting) and the rod diameter is 20 mm, find the Hydraulic pressure during the extending stroke Piston velocity during the extending stroke Cylinder kW power during the extending stroke Hydraulic pressure during the retracting stroke Piston velocity during the retracting stroke Cylinder kW power during the retracting stroke.

2. An 8-cm-diameter hydraulic cylinder has a 4-cm-diameter rod. If the cylinder receives flow at 100 Lpm and 12 MPa , find the a. Extension and retraction speeds b. Extension and retraction load-carrying capacities

3. Needle valve Flow is controlled in both the directions

4. Flow control valve (Needle valve with integral check valve) Throttle Check valves are used where volume flows have to be infinitely controlled in one direction while allowing for free flow in the reverse direction.
