Unit 2 Review Assignment 2

Question 1
Which of the following is NOT one of the three important considerations when analyzing or
designing a hydraulic circuit?
A. Safety of operation.
B. The quality of the air flowing through the system
C. Performance of desired function.
D. Efficiency of operation.
E. None of the above
Question 2
Which of the following is the purpose of a regenerative circuit?
A. To remove heat from the working fluid
B. To remove extra moisture from the working fluid
C. To control the volumetric flow rate
D. To speed up the extending speed of a single-acting cylinder
E. None of the above
Problem 1
A double-acting cylinder is hooked up in the regenerative circuit
shown. The relief valve setting is 110 bars. The piston area is 115
cm2 and the rod area is 60 cm2. If the pump flow is 0.0020 m3/s, find
the cylinder speed and load-carrying capacity for the
a. Extending stroke

b. Retracting stroke
