A person blows into the open-end of a long pipe. As a result, a high-pressure pulse of air travels down the pipe. When this pulse reaches the other end of the pipe

A

a high-pressure pulse starts traveling up the pipe, if the other end of the pipe is open.

B

a low-pressure pulse starts traveling up the pipe, if the other end of the pipe is open.

C

a low-pressure pulse starts traveling up the pipe, if the other end of the pipe is closed.

D

a high-pressure pulse starts traveling up the pipe, if the other end of the pipe is closed.

Text Solution

Verified by Experts

The correct Answer is:
B, D
At open end phase of pressure wave charge by `pi` so compression returns as rarefraction. While at closed end phase of pressure wave does not change so compression return as compression.

At the open end of organ pipe

Water at 20^(@)C is flowing in a horizontal pipe that is 20.0m long.The flow is laminar and the water completely fills the pipe. A pump maintains a gauge pressure of 1400Pa , at a large tank at one end of the pipe. The other end of the pipe is open to the air, The viscosity of water at 20^(@)C is 1.005 poise (a) If the pipe has diameter 8.0 cm , what is the volume flow rate? (b) What gauge pressure must the pump provide to achieve the same volume flow rate for a pipe with a diameter of 4.0cm ? (c) For pipe in part (a) and the same gauge pressure maintained by the pump, what does the volume flow rate become if the water is at a temperature of 60^(@)C (the viscosity of water at 60^(@)C is 0.469 poise?

Explain: if an observer places his ear to one end of a long iron pipe line, he can distinctly hear two sounds when a man hammers the other end of the pipeline.

A sound wave travelling along an air column of a pipe gets reflected at the open end of the pipe. What is the phase difference between the incident and reflected waves at the open end?

The air column in a pipe closed at one end is made to vibrate in its second overtone by a tuning fork of frequency 440 Hz . The speed of sound in air is 330ms^(-1) . End corrections may be neglected. Let P_(0) denote the mean pressure at any point in the pipe, and DeltaP the maximum amplitude of pressure variation. (a) What the length L of the air column. (b) What is the amplitude of pressure variation at the middle of the column? ( c ) What are the maximum and minimum pressures at the open end of the pipe? (d) What are the maximum and minimum pressures at the closed end of the pipe?

Two wave pulses identical in shape but inverted with respect to each other are produced at the two ends of a stretched string. At an instant when the pulses reach the middle, the string becomes completely straight. What happens to the energy of the two pulses ?
