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 human ears can hear frequencies up to
20,000 Hz)?
c) What will happen to the frequency in the late afternoon as the
air begins to cool?

A very long pipe is capped at one end with a semipermeable
membrane. How deep (in meters) must the pipe be immersed into the
sea for fresh water to begin to pass through the membrane? Assume
the water to be at 20.0°C and treat it as a 0.700 M NaCl solution.
The density of seawater is 1.03 g/cm3 and the acceleration due to
gravity is 9.81 m/s2.

A 0.726-kg rope 2.00 meters long
lies on a floor. You grasp one end of the rope and begin lifting it
upward with a constant speed of 0.710 m/s.
Find the position and velocity of
the rope’s center of mass from the time you begin lifting the rope
to the time the last piece of rope lifts off the floor.
Plot your results.
(Assume the rope occupies negligible
volume directly below the point where it is being lifted.)

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

Consider a pipe that is closed at one end. Sketch the standing
wave pattern in each of the following situations; showing the
regions of high and low air pressure variations (pressure antinodes
and pressure nodes). Then formulate equations that relate the
wavelength and frequency to the length of the pipe.
