संकल्पना:

प्रवाह दर = पिस्टन का वेग × पिस्टन का क्षेत्रफल 

\(Area\;of\;piston = \;\frac{\pi }{4}{d^2}\)

गणना:

दिया गया है,

प्रवाह दर = 0.3 m3/min = 0.3/60 m3/sec

पिस्टन का व्यास, d = 50 mm = 0.05 m

\(Area\;of\;piston = \;\frac{\pi }{4}{d^2} = 0.001963\;{m^2}\)

प्रवाह दर = पिस्टन का वेग × पिस्टन का क्षेत्रफल 

\(\frac{{0.3}}{{60}} = v \times 0.001963\)

v = 2.5466 m/s
