A beam of plane waves in water contains 50 W of acoustic power distributed uniformly over a circular cross-section of 50 cm diameter. The frequency of the waves is 25 kc/s. Determine (a) the intensity of the beam, (b) the sound pressure amplitude, (c) the acoustic particle velocity amplitude, (d) the acoustic particle displacement amplitude and (e) the condensation amplitude. Assume that the velocity of sound in water is 1450 m/s.

Solution:
A beam of plane waves in water contains 50 W of acoustic power distributed unifo
