A 0.5 meter long pipe is open on both ends. Assume the speed of
sound in air is 343 m/s.
A) What is the longest wavelength of sound that can be resonant
in the pipe?
B) What is the fundamental frequency of sound in this pipe?
C) What is the frequency of the 2nd and 3rd harmonic of sound in
this pipe?
D) What is the wavelength of the 2nd and 3rd harmonic of sound
in this pipe?
A tube of air open at only one end is vibrating in the 5th
harmonic from a tuning fork of frequency 120 Hz placed at the open
end. If this tube of air were to vibrate at its fundamental
frequency, what frequency, in Hz, tuning fork would be needed at
the open end
A pipe of diameter 350mm at one end and the diameter
at the other end is 200mm. The datum head is same for both ends.
Calculate
(i) Intensity of pressure at the smaller end if the pressure at the
bigger end is 40.5 N/cm2. (ii) Determine the head loss between
smaller end
and bigger end. Take discharge through the pipe as 40 litres/sec.
(iii) Scope for this obtained results of head loss between both
ends
the like that only!

A drainage pipe running under a highway is 20 meters long. One
end of the pipe is open and the other is clogged by debris. The
wind blowing across the open end causes oscillations in the
pipe.
a) If the speed of sound on that particular day is 340 meters
per second, what will be the fundamental frequency of oscillation
in the pipe?
b) What will be the frequency of the highest harmonic audible to
the human ear. (Assume that...
The end of a stopped pipe is to be cut off so that the pipe will be open. If the stopped pipe has a total length L, what fraction of L should be cut off so that the fundamental mode of the resulting open pipe has the same frequency as the fifth harmonic (n=5) of the original stopped pipe?
Express your answer in terms of L.

kg rock is hung from one end of a meter at the 0 cm mark so that
the meter is balanced as a balance when the filter is at the 25 cm
mark. From this information, what is the mass of the meter?
