Question

A Pneumatic cylinder has a bore of 200 mm and a piston rod diameter of 140 mm. For an extend speed of 5 m/min.
The flow rate from the full bore end on retract is

• A. $324Lpm$
• B. $309Lpm$
• C. $250Lpm$
• D. $289Lpm$

Answer 1

The correct option is B $309Lpm$

$\text{Flow from full bore end of cylinder}{Q}_R\text{is given by}Q=\frac{\pi }{4}\times (0.2{)}^2\times 0.164=0.00515m^3/sec=309Lpm$
