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.

Flow rate from the annulus side on extend

• A. $65Lpm$
• B. $80Lpm$
• C. $60Lpm$
• D. $70Lpm$

Answer 1

The correct option is B $80Lpm$

$\text{The flow rate of leaving liquid in given by}\frac{\pi }{4}\left(\right(0.2{)}^2-\left(0.14{)}^2\right)\times \frac{5}{60}=0.0013345m^3/sec=80Lpm$
