For a pipe open at both ends, fund frequency (Fo) given byFo = v /2L 

v = velocity of sound = 340 m/s (at about 20ºC) 

Fo = 340/2*5.34 = 31.8 Hz 


While for the one closed at one end and open at the other end...

For a pipe open at one end, fund frequency (Fo) given byFo = v/4L 

Fo = 340/4*5.34= 15.9 Hz
