WebThe reduction of a sound is called attenuation. The effect of distance attenuation depends on the type of sound sources. Most sounds or noises we encountered in our daily life are from sources which can be characterized as point or line sources. If a sound source produces spherical spreading of sound in all directions, it is a point source. WebAug 16, 2007 · Longitudinal stress in cylindrical tank = (pr)/ (2t). Hoop stress in spherical tank = (pr)/ (2t). where p = internal pressure of tank. r = radius of tank. t = thickness of tank wall. Based upon the above considerations, either it's because propane is stored under higher pressure, or it vaporizes more readily and will thus exert more pressure ... images of tulip bulbsWebThe pressure amplitude from a point source in free space falls off with range r as r −1; this geometric loss is called spherical spreading. Most sources of interest in the deep ocean are closer to the surface than to the bottom. Hence, the two main short-range paths are the direct path and the surface reflected path. images of tulane university
